Abstract
A clamping collar (10) constituted by a semi-rigid wire that is rolled up to form at least one turn (11) with a first end (12) thereof being provided with a hook (16) extending transversely to the plane of the turn and with a second end (14) thereof being folded back outwardly to form an extension (26) lying substantially in the plane of the turn. The extension (26) includes a fastening fold (28) forming a setback going towards the center of the turn, and it also includes a pre-fastening fold (32) situated between that end (24) of the extension (26) which is connected to the turn (11) and the fastening fold (28), said pre-fastening fold being analogous to the fastening fold.
