The socket body 1 is formed in a tubular shape, and the plug P
A push body 2 for pushing a valve body (not shown) on the side is inserted and fixed. A locking ball support ring 3 is slidably inserted over the outer periphery of the push body 2 over a certain range. The locking ball support ring 3 is biased by a spring 7 so as to project. Ball holes 5 are provided at three locations in the circumferential direction of the tip of the socket body 1, and locking balls 4 are loosely fitted in the ball holes 5. The operation ring 13 is urged toward the outer peripheral portion of the tip of the socket body 1 by a spring 14 so that the operation ring 13
By hitting the side wall of the inner surface concave portion 15 of the locking ball 4,
The operation ring 13 can be positioned at the retracted position. The locking ball 4 is movably inserted into the pusher 2 so that the locking ball 4 can be supported by the locking ball support ring 3 in its normal position. In FIG. 1, reference numeral 21 is a cap. Then, the plug P on the main plug (not shown) side
By inserting the socket A on the gas appliance (not shown) side into the socket, the locking ball support ring 3 is pushed against the spring 7, and the movement of the locking ball support ring 3 inserts it into the ball hole 5 of the socket body 1. The held locking ball 4 is moved to the inner side of the socket body 1, and the locking ball 4 is fitted into the outer peripheral groove C on the plug P side so that the socket A and the plug P can be connected. . The structure of the plug P and the socket A is well known as a joint for gas appliances. Then, connect the operating ring 13 in the connected state to the spring 1.

In such a case, by forming the fitting claw 11 at the tip of the stopper arm 8 extended from the spring receiver 6, the elastic displacement amount of the fitting claw 11 can be made sufficient, and the elastic displacement amount of the fitting claw 11 can be reduced. Since the fitting claw 11 does not come off from the fitting groove 12 due to the shortage, the pressing body 2
Can be attached to the socket body 1 with sufficient strength. In the figure, 22 is an O-ring.

[Effects of the Invention] In summary, according to the present invention, the pusher is provided with a spring receiver so that a spring for biasing the locking ball support ring to project is interposed between the spring receiver and the locking ball support ring. Extend a plurality of stopper arms to the outer peripheral side of the locking ball support ring, form an engaging claw on the inner surface of the tip of the stopper arm, and form an engaging recess on the outer surface of the locking ball support ring to engage the engaging claws. Since it engages with the fitting recess, the pressing body and the locking ball support ring can be integrated, the locking ball support ring can be held on the pressing body, and machining for holding the locking ball support ring can be omitted, Moreover, by integrating them, assembly can be done at once, and the assemblability can be improved, and multiple stopper arms extending from the spring bearing also serve as guides when the pressing body is inserted into the socket body, locking balls Support Since the engaging recess on the outer surface is deeper than the length of the engaging claw, the fitting claw on the top of the tip of the stopper arm fits inside the socket body when the pressing body is inserted into the socket body. The engaging claws go deep into the deep engaging recesses to prevent the fitting claws from sliding strongly against the inner peripheral surface of the socket body, and the pressing body can be lightly and easily inserted into the socket body. Also in this respect, the assemblability can be improved, and since the fitting claw is formed at the tip of the stopper arm extending from the spring receiver, the elastic displacement of the fitting claw can be made sufficient. There is an advantage that the pressing member can be attached to the socket body with sufficient strength without the fitting claw coming off the fitting groove due to the insufficient elastic displacement of the fitting claw.
