DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is an exploded front view of a clamp 25, and FIG. FIG. 3 is a front view of a state in which the locking portion 26 of the bracket locking portion 15, the mounting hole 2 a of the bracket 2, and a second rotation locking portion 27 formed to extend to the rotation locking portion 9 of the holding member 6. FIG. 4 is an explanatory diagram of the relationship with the following. The binding portion 4 of the clamp 25
Mounting member 5 and holding member 6 and bracket fitting portion 11
Are configured in substantially the same way, with some of them changed and the same parts are given the same reference numerals and the changed parts are described in detail.

[0010] The clamp 25 of this embodiment is similar to the conventional one in that
The mounting member 5 and the holding member 6 are formed in a substantially cylindrical mating shape having a predetermined diameter via a hinge portion 7.
A locking claw 26 formed on the bracket locking portion 15 formed on the bracket fitting portion 11 formed on one end of the bracket 2 and engaged with the mounting hole 2a of the bracket 2 is formed as shown in FIG. I have. Mounting hole 2 penetrated through this bracket 2
The engaging claw 26 to be engaged with the conventional engaging claw 16 is formed in a shape to be fitted and engaged with the entire triangular engaging hole 2a. The retaining claw 26 is formed in a small, similar triangular shape that engages with a part of the vertex side of the inverted triangular mounting hole 2a.
The remaining hole 2c is formed on the bottom side 2b side of a.

A predetermined width (a side of the mounting hole 2a of 10 mm) is formed at the center of the upper end of the rotation locking portion 9 formed on the holding member 6 side.
A second rotation locking portion 27 having a predetermined length is formed to extend upward, and the second rotation locking portion 27 projects to the opposite side of the locking claw 10 and A claw body 28 having an inclined guide surface 28a that fits and engages with the remaining hole 2c of the mounting hole 2a, that is, the bottom side 2b is formed.

When the bracket 2 of the groove 17 on the side of the bracket engaging portion 15 of the bracket fitting portion 11 is inserted into the clamp 25 formed as described above, the clamp 25 is protruded from the bracket engaging portion 15 and the engaging claw 26 Is an inverted triangular mounting hole 2a
Is elastically engaged on the vertex side. Then, the concave portion of the corrugated tube 1 is fitted into the rib 8a in the mounting member 5 in the same manner as described above with the wire harness W into which the corrugated tube 1 is externally fitted in a bent shape R, and the holding member 6 is further connected via the hinge portion 7. When the second rotation locking portion 27 formed on the front end side of the second rotation locking portion 27 is inserted from above the groove portion 17 side, and the rotation locking portion 9 is further inserted, the second rotation locking portion 27 on the front end side is inserted. The claw body 28 is guided by the end edge of the bracket 2 via the guide surface 28a, and rides on the bracket 2 to be elastically deformed. When further inserted, the claw body 28 faces the remaining hole 2c of the mounting hole 2a and is elastically restored at the same time. The claw body 28 is elastically engaged with the remaining hole 2c. At the same time as the engagement of the claw body 28, the locking claw 10 of the rotation locking portion 9 is engaged with the engaging claw 21 of the clamp locking portion 20, and the clamp 25 is locked and fixed to the bracket 2 so that the wire harness W Is disposed at the bending portion R.

As described above, the holding member 6 of the clamp 25 has the rotation locking portion 9 formed at the end thereof and the second rotation locking portion 27 extending from the locking portion 9. The claw body 28 of the second rotation locking portion 27 is fixed to the remaining hole 2c in which the bracket locking portion 15 of the mounting hole 2a of the bracket 2 is locked.
And the rotation locking portion 9 is locked at two positions where the rotation locking portion 9 is locked to the clamp locking portion 20. When the reaction force of the bent portion R of the wire harness W acts on the clamp 25 and the engagement between the clamp engagement portion 20 and the rotation engagement portion 9 is displaced in the disengaging direction, the rotation engagement portion 9, the second rotation locking portion 27 is engaged with the lower mounting hole 2a side. Therefore, the second rotation locking portion 27 is prevented from moving in the disengagement direction and can be prevented from disengaging. Short circuits and the like can be prevented. In addition, since the shape of the clamp 25 is only the formation of the second rotating member 27 and the formation of the locking claw 26 of the bracket locking portion 15 in a slightly smaller similar triangular shape, it is necessary to make many types of changes. In addition, there is an economical advantage that the existing bracket 2 is used for compatibility.

[0014]
