However, when a washer tube is also wound around one band clip at the same time to be locked to the vehicle body, in the band clip 1, the band 4 is used to fasten the washer tube T together with the wire harness W / H. Therefore, a strong tightening force may be applied to the washer tube T, and the washer tube T may be crushed as shown in FIG. 7 (C). If the tightening force of the band is weakened to avoid the crush of the washer tube T, the wire harness W
The fixing force for / H also weakens, causing problems such as displacement. Therefore, there is a problem in that it is very difficult to adjust the tightening force of the band 4 and it takes a lot of work.

Further, since the body portion 2, the vehicle body engaging portion 3 and the band 4 of the band clip 1 are integrally formed, when the plate thickness of the vehicle body and the shape of the engaging hole are different,
In order to support this, it is necessary to create a wide variety of hand clips. Further, when either the vehicle body engaging portion 3 or the band 4 is worn or damaged, the hand clip as a whole must be discarded. Therefore, there is a problem that the material cannot be effectively used and the cost becomes high.

The present invention has been made in view of the above problems, and relates to a band clip wound around and fixed to a wire harness and a washer tube. The main issue is to provide a wire harness band clip that can be wound and fixed, and the secondary issue is to provide a wire harness band clip that can effectively use the members.
