Abstract: A clasp is provided for a jewelry chain, particularly a chain adapted to hold interchangeable designer elements. The clasp has a male and a female member, the male member locking within the female member and being so sized that, when the clasp is opened, the interchangeable beads are easily slid over it and onto the chain; the female member is sized so as to prevent the decorator elements from being removed from the chain. The male member is preferably a spring which is depressed for insertion into the female member, the spring action causing a portion of the male member to lock with a portion of the female member.
