ABSTRACT:
A clasp for connecting the ends of jewelry members is disclosed. The clasp of the present invention comprises an elongated main body member, a cooperating member for detachable connection to the main body member, and securing the cooperating member in the main body member such that the cooperating member does not dissociate from the main body member. The main body member has an aperture in one end and an elongated slot which terminates in an enlarged end on one end and connects to the aperture on the opposite end. The cooperating member has a spherical portion on one end, an eyelet portion on the opposite end, and a shank portion connecting these two portions. In the one embodiment of the present invention, securing is accomplished by a flat spring which is mounted adjacent to the slot in the main body member and extends partially over the slot to bias the cooperating member into the main body member and against the aperture. In another embodiment securing is accomplished by a helical spring being mounted in the main body member with a biasing ring that biases the cooperating member outwardly against the aperture. In another embodiment a path in the slot that is offset from the longitudinal axis of the main body member accomplishes securing. In operation, the spherical portion is inserted into the enlarged end such that the shank portion extends through the enlarged end. The shank portion of the cooperating member is then pulled through the slot and downwardly into the aperture of the main body member. Such securing prevents the cooperating means from dissociating from the main body member.
