ABSTRACT:
This adjustment device comprises an adjustment link (6) provided with two parallel articulation axes (5,7) transverse to a bracelet, each serving to connect this adjustment link to two elements of the bracelet forming an endless attachment. This adjustment link is able to pivot about one of its axes (5) to that their respective positions are inverted, these two positions thus corresponding to two determined lengths of the bracelet. In the shorter adjusted position, the adjustment link (6) elastically engages in a recess (8c) of one of the articulated elements (8) of the adjustment link (6) by pressing this element (8) in the direction of the arrow (F.sub.7) so that the adjusted position is maintained as long as the adjustment link (6) has not moved out of the recess (8c) in which it is elastically held by the locking means (8d) of the recess (8c).
