Buckle

Abstract

A plug member of a buckle has a pair of engaging legs receivable in a socket member to couple the plug member and the socket member. The engaging legs are curved inwardly toward each other and each of which has an elongated opening extending longitudinally thereof and extending across its thickness. The socket member includes an upper plate and a lower plate defining therebetween a guide chamber and interconnected by a central guide wall. The socket member includes a pair of retaining portions disposed in the guide chamber for interlocking engagement with a pair of locking portions formed at the leading ends of the respective engaging legs. Each of the engaging legs each has a recessed thin guide portion which is smaller in thickness than an operating portion of each engaging leg. The buckle thus constructed is relatively small in thickness, can be coupled and uncoupled reliably and smoothly with a relatively small force, and is able to withstand undue force or pressure tending to damage the buckle.
