<p>A multi-purpose clasp designed to be used as an universal clasp of jewelry, ornament chains, key chains, fishing lines and the like. The clasp is one-piece in structure, comprising a locking bow (1), a spiral neck (2) and a connection ring (3); in its simplest embodiment it is open-jointed, and in its further developed embodiment it comprises a parallel connection. At the locking stage, a point portion (1') of the locking bow (1) of the clasp of the simplest embodiment is positioned within the connection ring (3) so as to be protected from catching external objects and so that it partly covers the open joint of the connection ring (3); in the further developed form, a hook-shaped tip (1'') of the locking bow (1) is pressed within a bent end portion (3'') of the connection ring (3) to be protected from catching, so that it simultaneously locks the connection ring (3), closes the connection opening (3') and secures the locking of the locking bow (1). Since the manufacture of the clasp can be effected without any heat treatment and the attachment to the object can be made without soldering, the clasp can be made of any resilient material resistant to bending.</p> |
