DEVICE FOR ATTACHMENT BY STAPLING

A clamping fastening device for assembling a part (7) to a support part (18), comprises a fastening clip including a deformable hooking element which defines a clamping face (12), this hooking element being intended to be pushed through the part and the support part and being designed with a clamping face that retracts elastically inward toward the clip. It further comprises a control indicator (4) for proper installation of the clip in the clamping position in the form of a rod which is constrained to retract under the effect of the retraction of the clamping face so as to be able to begin to be driven into the clip.
