The above-mentioned conventional binding band has a plurality of recesses which are recessed at predetermined intervals along the length direction thereof. The conventional clip body has a head portion having the insertion hole and a leg portion extending from the head portion and capable of being locked to the panel.

[0004]

However, the above-mentioned conventional harness clip has a problem in that the insertion hole is relatively small and it is difficult to insert the binding band. That is,
A conventional insertion hole has a pair of wall portions facing each other in the thickness direction of the binding band.

A claw portion is provided on one of the two wall portions. In addition, the facing interval between both wall portions was made to substantially match the thickness of the binding band. For this reason, in the conventional insertion hole, the binding band is difficult to insert because the facing interval between both wall portions is narrow. Therefore, the invention according to claim 1 is made in view of the problems of the above-described conventional technology,
The purpose is to have the following two points.

The first object of the present invention is to widen the facing distance between both wall portions of the insertion hole to facilitate insertion of the binding band. Secondly, in view of the fact that the engagement force at the location of the claw portion decreases when the facing distance between both wall portions of the insertion hole is widened, the pressing piece facing the claw portion is provided. By providing it, it is possible to prevent a decrease in the engaging force.

[0007] The second aspect of the present invention is the first aspect of the present invention.
In addition to the object of the described invention, the following two points are intended.
Firstly, an object of the invention of claim 2 is to position the claw portion on the outlet side of the insertion hole and to provide a pressing piece also on the inlet side of the insertion hole, whereby a pressing piece positioned on the inlet side is provided. By the pressing piece located on the outlet side facing the claw portion, the bending of the binding band in the insertion hole is prevented, and the engagement force is further reduced.
The point is that it can be surely prevented.

Secondly, the object of the invention as set forth in claim 2 is to position the pressing piece on the inlet side of the insertion hole, thereby narrowing the facing interval of both wall portions of the insertion hole, but the pressing piece of the binding band. By protruding toward the center in the width direction, the binding band is improved in insertability. That is, since the facing distance between both wall portions of the insertion hole is set wider than the thickness of the binding band as a whole, excluding the pressing piece,
Even when the binding band is obliquely inclined about the contact point between the binding band and the pressing piece, the binding band can be inserted along the pressing piece located on the inlet side. Further, even when the binding band is curved from the center in the width direction, the binding band can be inserted along the pressing piece located on the inlet side.

The invention according to claim 3 is the above-mentioned claim 1.
Alternatively, in addition to the object of the invention described in 2, the following objects are intended.
That is, the object of the invention as set forth in claim 3 is to prevent the bending of the binding band in the insertion hole by providing the pressing piece along the insertion direction of the binding band, and to further surely prevent the decrease of the engaging force. The point is that I was able to do it.
