In order to solve the above-mentioned problems, in the present invention, the band clip of the above-mentioned type is engaged behind the front end of the clip piece so that the clip piece engages with the clip band. A holding means is provided to prevent bending in the uncoupling direction. In one aspect of the present invention, the holding means is composed of an insert piece inserted between the clip piece and the base portion. It is preferable that the insertion piece has an integral structure in which it is connected to the base portion by a flexible string piece, but it may be configured as a part separate from the base portion.
In another aspect of the present invention, the base portion of the clip is provided with a stud engaging portion that engages with a stud provided on the panel, and is attached to the panel by engaging with the stud. When the stud engaging portion of the base portion is engaged with the stud on the panel, the base portion is pushed outward in the radial direction by the stud and engages behind the tip portion of the clip piece. An elastic blocking piece is provided to prevent the piece from bending in the disengagement direction with the clip band. According to still another aspect of the present invention, the base portion of the clip has a leg portion that is inserted into an insertion hole formed in the panel, and is attached to the panel by inserting the leg portion into the insertion hole of the panel. . When the leg portion is inserted into the hole of the panel, the base portion is pushed by the panel and engages behind the tip portion of the clip piece, and the clip piece bends in the disengagement direction with the clip band. An elastic blocking piece for blocking is provided.

[0005]

According to the above-described configuration of the present invention, the base portion of the band clip is engaged behind the tip of the clip piece to prevent the clip piece from bending in the disengagement direction from the clip band. Since the holding means is provided, even if the flexural rigidity of the clip piece is low, the clip piece is not bent by an external force in the attached state, and the holding force can be increased. In the structure in which the elastic blocking piece that is pushed outward in the radial direction by the stud when the stud is attached and engages behind the tip end of the clip piece is attached to the base portion, the operation of attaching the band clip to the stud is sufficient. The bending can be stopped. Further, when the leg portion is inserted into the hole of the panel, the leg portion is pushed by the panel and engages behind the tip end portion of the clip piece, and prevents the clip piece from bending in the disengagement direction with the clip band. In the configuration in which the elastic blocking piece is provided, the bending of the clip piece can be blocked only by inserting the leg portion of the band clip into the hole of the panel.
