Abstract
Abstract A buckle comprises a plug member and a socket member relasably engageable therewith, the plug member including a retainer means in the form of a disc-like collet and a stopper means adapted to hold the retainer means stationery after the latter is rotated into position in the body of the plug member. The retainer means is normally urged upwardly by a coil spring and serves as a fulcrum about which the plug member and the socket member can be moved rotatably relative to each other.
