Abstract

A safety clasp which may be used in particular for a necklace or bracelet chain, comprises two pieces sliding one in the other, namely an outer sleeve and a slide element housed inside the sleeve. The sleeve has hooked thereto, at one end, the first end link of a chain. The sleeve also has a slot which defines a transverse arm opening and a connected longitudinal arm opening which extends in the direction of the end of the sleeve opposite to where the first end link is hooked. The sleeve is adapted to move longitudinally with respect to the sleeve and presenting, in its rear part, a notch for receiving the second end link of the chain. The inner slide element presents, in its front part opposite that part where a notch is provided, an elastically deformable arm terminating in a tooth engaging in a hole for locking provided in the wall of the sleeve. Consequently, in position of closure, in which the tooth of the arm is engaged in the hole for locking, the second end link is retained by the rear edge of the notch in the sliding element, being maintained spaced apart from the end of the longitudinal arm of the slot in the sleeve.
