<p>The clasp has a fastening system provided with a lever (2) for locking arms (7, 8). The lever is pivotably mounted on a cap (1) by a hinge i.e. small pin (3a), where the lever controls a bolt (4) that is pivotably mounted on the cap by another hinge i.e. small pin (3b), distinct from the former hinge. The bolt engages with a hook (22) fitted to one of the arms and locks the clasp when the clasp is pushed to a fastening position. An elastic unit i.e. plate (5) is arranged to hold the lever in a non-raised position and the bolt engaged with the hook when the lever is not manually activated.</p> |
