プリング等の受筒から素抜けることがあった。(Prior art) Connecting conduits is not easy. In particular, in the case of polyethylene conduits, it is impossible to connect them with adhesives, so troublesome methods such as screwing or wrapping tape are used to connect them to receivers such as boxes, connectors, or couplings. Ta. However, in addition to being time-consuming, the connection was not sufficient, and the conduit sometimes slipped out of the receiver of the box, connector, or coupling.

と同様に弧状にされている。(Configuration) (1) is a receiving cylinder, which may be used as a connector as in the example shown in Fig. 1, or as a coupling as in the example shown in Fig. 2; Further, as shown in the example shown in FIG. 8, the device may be manufactured and used integrally with an electrical wiring box such as an outlet box or a switch box, or even with a hub. The receiving tube (1) should be of any type that allows the electrical conduit to be inserted through it. Preferably, the receiving tube (1) is made of synthetic resin. It may be a conduit and a smooth conduit (2), or it may be a corrugated conduit (3) in which peaks and valleys are alternately formed on the outer surface as shown in the example shown in FIG. In Fig. 9, (4) is the receiving tube (1
) is a recess provided in the peripheral wall of the receiver (1) facing inward, and it is desirable that this recess (4) be provided on the side of the tip opening (5) of the receiver (1). In the case of the example shown in FIG. 9, the inner surface (4a) of the recess (4) is the inner surface (1a) of the receiving tube (1).
It is also arcuate.

（６）は合成樹脂から作製することが望ましい。In Figures 4 and 5, (6) is a locking piece having a claw (7) at the tip, and this locking piece (6) is shown in Figures 8 and 9.
As shown in the figure, it is movably fitted into the recess (4). As in the examples shown in FIGS. 8 and 9, the locking piece (6) may be movable in the circumferential direction of the receiver WJ (1), that is, in the direction of the arrow (8) and the direction of the opposite arrow (8). desirable. The locking piece (6) is preferably made of synthetic resin.

能を達成するかぎシ適宜変更できる。Under normal conditions, the locking piece (6) fitted into the recess (4) has a claw (7) that moves from the inner surface (1a) of the receiving tube (1) to the inner surface of the receiving tube (1), as shown in FIG. It is made so that it does not protrude in any direction. On the other hand, when the locking piece (6) is moved within the recess (4), the claw (7) engages with the inner surface (1a) of the receiving tube (1) as shown in FIG.
) The yoshi is also made to protrude inward. That is, the reason why the locking piece (6) is moved is to cause the claw (7) of the locking piece (6) to protrude inwardly from the inner surface (1a) of the receiving tube (1). Therefore, the moving distance and moving direction of the locking piece (6) can be changed as appropriate to achieve the function of causing the claw (7) to protrude inwardly from the inner surface (1a) as well.

ら簡単に判別できる利点がある。In the case of the example shown in the drawings, a recess (4b) forming a part of the recess (4) is provided to penetrate the peripheral wall of the receiving tube (1), and a projection (6a) is provided on the stop piece (6). The stop piece (6) can be moved by operating a protrusion (6a) fitted into the recess (4'b) with a finger or the like from outside the receiving tube (1). In this case, the movement of the stop piece (6) is
This is convenient because it can be operated from the outside of the receiver, and there is also the advantage that whether or not it has moved can be easily determined from the outside of the receiver without the need to look inside the receiver.

（２） （３）は外れぬ様に受筒（１ンに連結される。Now, a typical procedure for connecting the electric conduit (2) or the corrugated electric conduit (3) to the receiving tube (1) will be explained. first,
The locking piece (6) is fitted into the recess (4) so that the claw (7) of the locking piece (6) does not protrude inward of the receiving tube (1). Next, connect the conduit tubes (2) and (3) to the receiving tube (1) and the opening at the tip (5).
Insert from. After that, the locking piece (6) fitted into the recess (4) is moved, and in the case of the example shown in Fig. 9, it is moved in the direction of arrow 8, and by this movement, as shown in Fig. 9. Insert the claw (7) of the locking piece (6) into the inner surface (1a) of the receiver (1).
) to protrude inward. Then, the claw (7) Hiro electric conduit (
2) It hooks onto the outer surface of the peripheral wall of (3), thereby connecting the stain ray tubes (2) and (3) to the receiving tube (1) so that they do not come off.

あるからである。これに対処するにはロック機構（９）
を設け、爪（７）を受筒（１）の内方に突出させたまま
の状態に係止片（６）を保持すれば良い。By the way, when connecting in this manner, it is preferable to prevent the moved locking piece (6) from returning to its original state. The reason for this is that due to external force or other circumstances when inserting the conduit tubes (2) (3), the locking piece (6) returns to its original position and the claw (7) does not protrude inward. If this happens, the conduit tubes (2) and (3) may easily fall out from the receiver tube (1).To deal with this, the locking mechanism (9)
, and hold the locking piece (6) with the claw (7) projecting inward of the receiving tube (1).
第４図〜第７図に示す例の様にロック機構（９）は凹部
−及び凸部（１１）から構成するととが望ましい。It is preferable that the lock mechanism (9) is composed of a concave portion and a convex portion (11) as in the examples shown in FIGS. 4 to 7.

When the locking piece (6) is moved, the concave part 00 and the convex part αυ are fitted into each other and locked. In the case of the examples shown in FIGS. 4 to 7, since the convex portion αp is particularly hemispherical, the work of locking the concave portion αQ and the convex portion (b) can be easily performed. Also, Figures 10 to 12
It is also desirable that the locking mechanism (9) be constructed from a narrowed portion (b) as in the example shown in the figure. Narrowing part (2) Cane, hollow part (4)
This is constructed by narrowing the portion where the locking piece (6) moves. The narrowed part (2) is connected to the locking piece (6
) moves by force.
従って一且係止片（６）の移動が完了したならば、狭搾
部（２）によって係止片（６）は確実にロックされる。Therefore, once the movement of the locking piece (6) is completed, the locking piece (6) is reliably locked by the narrowing portion (2).

誤まってした場合であっても、ロックを解除すれば電線
管の取シ外しも行ない得て便利である。In the case of the example shown in FIGS. 10 to 12, the depression (4b) forming a part of the depression (4) is made into a trapezoid shape, two of which are connected, and the narrow part of the connection part is narrowed. It is called the Department (B). Then, the trapezoidal protrusion (6b) protruding from the locking piece (6) is moved to move the narrowed part (2) (using the elasticity of the synthetic resin),
This allows the protrusion (6b) to be connected to the trapezoidal depression (4b) at the front.
Fit it inside. In this state, the locking piece (6) is located at the narrow part (6).
so that the conduit (2) (3
) is securely connected to the receiver (1) so that it does not come off.The locking mechanism (9) is not limited to the example shown in the drawings and can be modified as appropriate. If the locking piece (6) is kept protruding inward, it will cause the lock to break.Although it is not shown, if a lock release mechanism is provided, it will prevent the conduit from being accidentally connected. However, if you release the lock, you can conveniently remove the conduit.
