ABSTRACT:
A clasp includes releasably interconnectable first and second clasp members. The first clasp member has a hollow, cylindrical shape with first and second ends and a side wall. The second clasp member includes a hollow, cylindrical outer tubular member with opposed first and second ends. A first inner tubular member is slidably disposed within the first end of the outer tubular member. A second inner tubular member is mounted in the second end of the outer tubular member. A biasing spring mounted within the outer tubular member normally biases the first inner tubular member to a longitudinally outward position with respect to the first end of the outer tubular member. In one embodiment, the second inner tubular member is fixedly mounted within the second end of the outer tubular member. In another embodiment, the second inner tubular member is slidably mounted within the outer tubular member. Lock members are mounted on the first and second inner tubular members and releasably engage complimentarily-shaped lock receiving members formed on the first and second end walls of the first clasp member for releasably locking the first and second clasp members together.
