Abstract: A clasp with an interchangeable ornament includes a generally solid male clasp piece which is split longitudinally in a manner that it is transversely resilient, like a clip. A hollow female clasp piece has an insertion opening and an inwardly indented shoulder or lip at the insertion opening. When the male clasp piece is inserted into the female piece the shoulder of the female piece locks into a groove formed in the male clasp piece. Longitudinally extending slits in the peripheral wall of the female piece makes it transversely elastic and enables it to tightly hold an interchangeable ornamental sleeve that is fitted over the female piece. The ornamental sleeve in turn prevents the slit peripheral wall of the female piece from separating and assures that the inwardly indented shoulder remains locked in the groove of the male piece.
