<p>The buckle (F) consists of a base part (F1), attached to one side of the footpocket of the fin (P) and comprising a movable strap-locking tooth (22), counteracting elastic means (24), associated to said tooth (22) and manual strap-releasing means (17) connected to said tooth, and of a strap-fastening part (F2), which only comprises strap-guiding means (13) for returning the strap (C), and is joined to the base part (F1), in such a way as to be able to slide in the longitudinal direction of the strap (C) between a retracted strap-tightening position, wherein it is automatically hooked to the base part (F1), so as to be manually releasable, and the strap-locking tooth (22) is engaged with the teeth (C1) of the strap (C), and a forward quick strap-loosening position, wherein the strap-locking tooth (22) is disengaged from the teeth (C1) of the strap and allows the latter to slide freely in both senses. <IMAGE></p> |
