Abstract: A clasp includes a keeper assembly to one end of a belt or strap or the like and an engaging member attached to the other end of the belt or strap. The keeper includes a pair of arms having at least two retaining members mounted thereon. At least one of the retaining members is movably mounted on the arms. One or more springs are positioned so that they operate on the retaining members biasing them against each other. In another embodiment, the keeper assembly includes a housing having a channel for receiving the retaining members. In preferred embodiments, the engaging member includes a locking tab that is disposable between two of the retaining members to engage the engaging member to the keeper. In preferred embodiments, the locking tab has an enlarged tip and is recessed on its sides according to the contour of the retaining members. These two features, together with the action of the springs or biasing members, cooperate to secure the engaging member to the keeper assembly.
