ABSTRACT:
A buckle has a cover rotatably connected to an end of one of bands, a middle plate rotatably connected to the cover, and a bottom plate rotatably connected to the middle plate and rotatably connected to the other band. A guide housing is secured to an underside of the cover, and a pair of push plates are slidably mounted in the guide housing. A spring is provided between the push plates for outwardly urging the push plates respectively. A slant is formed on an engaging projection of the push plate. A pair of lugs are formed on the bottom plate. Each of the lugs has an engaging hole and is arranged such that the lug is engaged with the slant so as to inwardly move the push plate, and that the engaging hole engages with engaging projection of the push plate, thereby coupling the buckle. A leaf spring is provided for urging the cover in a disengaging direction.
