A buckle includes a base consisting of a base plate having an open hole formed therein on the longitudinal one end side thereof and opposite guide grooves formed therein on both sides thereof, a socket consisting of a plate-shaped body having a projection with an aperture formed integrally therewith on an opposite end to a belt connecting portion thereof, the projection being fitted in the hole formed in the base plate, and a plug consisting of a plate-shaped base body adapted to be slidably moved along the guide grooves of the base and having resilient pieces formed one end thereof and engaged with the aperture of the socket in snap-fit fashion and disengaged therefrom, wherein the resistance to sliding of the plug on the base becomes large when the resilient pieces of the plug are located out of the hole formed in the base plate.

A buckle comprising: (a) a base consisting of a base plate having an open hole formed therein on the longitudinal one end side thereof, a portion for connecting a first belt, said first belt connecting portion being formed in the base plate on the other end side thereof, and opposite rising pieces formed integrally therewith on both sides thereof, each rising piece having an inward projection piece formed integrally with said rising piece on the uppermost part thereof so as to form a guide groove thereat; (b) a socket consisting of a plate-shaped body having a portion for connecting a second belt, said second belt connecting portion being formed in the plate-shaped body on one end thereof, and a projection formed integrally with the plate-shaped body on the other end side thereof, said projection being fitted in said hole formed in the base plate and having an aperture formed therein so as to be parallel to an upper surface of the plate-shaped body; and (c) a plug consisting of a plate-shaped base body adapted to be slidably moved along said guide grooves formed at both sides of the base and having resilient pieces formed integrally therewith an extending from one end thereof, the resilient pieces being adapted to be engaged with said aperture of the socket in snap-fit fashion and disengaged therefrom, and further having a portion for connecting a third belt, the third belt connecting portion being formed in said plate-shaped base body on the other end side thereof; (d) said base plate of the base further having first, second and third grooves formed respectively in positions therein at both sides thereof, said grooves in each side being rectilinearly arranged at predetermined intervals in the longitudinal direction of said base plate, a first engaging portion formed between said first groove and said second groove, and a second engaging portion formed between the second groove and said third groove, and wherein said plug further comprises a pair of engaging pieces at both sides of said plate-shaped base body thereof, respectively, each engaging piece being formed at a longitudinally intermediate portion of the plate-shaped base body and projecting downwards so as to be slidably inserted into said first, second and third grooves of said base plate of the base and engaged with said first and second engaging portions of the base plate; wherein the respective sliding portions of the base and the plug are arranged such that the resistance to sliding of the plug on the base becomes large when the resilient pieces of the plug are located out of the hole formed in the base.
