<p>1. Tightening band (1) comprising a substantially annular and open bracelet (2) constituted by a material, in particular a metal, which is elastically deformable so that when it is not in use the annular bracelet remains partly open, and tightening means associated with said bracelet in order to allow the closing-up of the ends of the latter and the tightening of the bracelet, said tightening means comprising, on the one hand, a threaded rod (6) which is provided with an enlarged head (7) at its free end and which cooperates by screwing with a member (5) for supporting the threaded rod supported, at one end or in the vicinity of one end of the open bracelet, in order to be able to pivot about an axis substantially parallel to the axis of the bracelet, the rod extending substantially transversely to this pivot axis, and, on the other hand, a retaining member (8) which is supported on the other end or in the vicinity of the other end of the open bracelet and which comprises a through-notch (9) disposed and dimensioned so that the threaded rod (6) can be engaged therein and that the enlarged head (7) of the latter bears against the surface of the retaining member directed away from the other end of the open bracelet, in order that a rotation of the threaded rod causes closing-up or opening of the two ends of the bracelet and thus respectively tightening or loosening of the latter, characterised in that the end of the notch intended to co-operate with the enlarged head of the threaded rod has an enlargement (9b) which has a sufficient transverse dimension and which is shaped to receive all or part of the enlarged head (7) and in which this enlarged head (7) remains engaged, once it is introduced therein, under the action of the elasticity of the material constituting the bracelet, which tends to elastically separate the two ends of the latter one from the other.</p> |
