The belt main body 1b is integrally attached with a sandwiching member 2 for sandwiching and supporting a hose or the like (not shown).

According to such a configuration, by adjusting the overall length of the belt body 1b to the expected maximum outer peripheral length of the support body, after selecting and winding an appropriate support body, the extra length portion of the belt body 1b is removed. Since it can be cut, it is not limited by the outer peripheral length of the support.

Second Conventional Example In FIG. 11, a belt 1 similar to that of the first conventional example is provided, and a sandwiching member 3 for sandwiching and supporting a hose or the like is provided on a protrusion 1d provided on a belt body 1b. It is detachably and rotatably attached.

According to such a configuration, since a plurality of types of sandwiching members 3 are prepared in advance and the sandwiching members 3 can be selectively used according to the shape of the hose or the like, the flexibility of the shape of the hose or the like is high. There are advantages such as.

(Problems to be Solved by the Invention) However, in the first conventional example, since the sandwiching member 2 is fixed on the belt body 1b, the direction and shape of the sandwiching member 2 are changed. It is unavoidable to make it constant, for example, (I) If the crossing angle of the hose or the like with respect to the support is changed or the shape of the hose or the like is changed, it is necessary to remanufacture the entire fastener. There was a problem in terms of cost.

Also, (II) When the support and other structures are close to each other,
In this approaching place, it becomes difficult to engage the ratchet eye 1a with the ratchet engaging part 1c or cut the extra length part, and in the worst case, avoid this place and lock the hose etc. There was a problem in terms of workability.

On the other hand, in the second conventional example, there is flexibility in changing the crossing angle of the hose or the like with respect to the support and the shape of the hose or the like, and although the problem (I) is solved, the sandwiching member 3 Since it is still attached to the belt body 1b at a predetermined position, the problem (II) cannot be solved.

(Object of the Invention) Therefore, the present invention solves the above problems (I) and (II) by attaching a slidable member to the belt body and detachably attaching a member for supporting the supported member to this member. The goal is to work together.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention comprises a belt wound around a predetermined support in a tightened state and an elastic material for removably sandwiching a supported member. A sandwiching member and an intermediate supporting member made of an elastic material that is slidably attached to the belt body are provided, and a circular cut portion is formed in one of the sandwiching member and the intermediate supporting member and a columnar portion is formed in the other. The circular cut portion is characterized in that the size of the cut portion is enlarged so that the cylindrical portion is taken in or released inside when a force of a predetermined magnitude or more is applied.
