ABSTRACT:
A safety clasp for necklaces, bracelets and the like is provided with a leaf spring member having its ends canted outwardly so as to enter and engage receiving apertures formed in an outer member. Retaining rings are provided at each end of the separable clasp with the outer member having an outer tubular sleeve with an open and a closed end and with apertures formed intermediate its length. An inner member is slidable and rotatable within the outer member and carries the leaf spring by a spine member with said spring secured at its midlength at the inner end of the spine. Receiving means for the leaf spring is provided in and along the spine and a bias such as a coil spring is secured at the closed end and internal of the outer member to urge the inner member outwardly. A quarter-turn of this inner member is made to bring the ends of the leaf spring from in way of the apertures formed in the outer member.
