ABSTRACT:
A rivet (1) includes a bearing head (2), a pulling stem (3) and an insertion body (4). The insertion body (4) includes at least two longitudinal flat surfaces (13) interrupting a notched portion (14); and at least two elastic feet (15) each having a first end elastically joined to the insertion body (4) and a second end which is free. Each of these elastic feet (15) is adapted to adopt a folded position in which it is folded along the insertion body (4), on one of the flat surfaces (13), and a tightened position in which it is arranged transversely of the general orientation of the insertion body (4). The bearing head (2) has at least one slot (9) enabling the head to deform radially.
