A buckle comprises a male member having a pair of resilient legs releasably engageable with a socket portion of a female member to couple the male and female members, the female member having a pair of cantilevered resilient arms resiliently flexible toward each other to urge the legs out of interlocking engagement with the socket portion. The arms are disposed between a pair of opposed plates of the socket member and have stop fingers loosely received in apertures in one of the plates. With this construction, the resilient arms are protected against damage or breakage when subjected to forces tending to flex the arms in a direction either parallel to or perpendicular to the general plane of the socket portion. The male member includes a generally U-shaped reinforcing rib disposed between and connected with the legs with a U-shaped slit defined therebetween so as to increase the resiliency of the legs.

A buckle for fastening two end portions of an article, comprising: (a) a male member adapted to be connected to one of the end portions of the article and including a pair of resiliently flexible legs having a pair of abutment surfaces; and (b) a female member adapted to be connected to the other end portion of the article and including a socket portion couplable with said legs, said socket portion including (1) a pair of opposed plates and a pair of spaced guide walls projecting from an inner surface of one of said plates toward the other plate and extending longitudinally of said plates so as to define therebetween a central slot for receiving therein said legs, and a pair of lateral grooves disposed on opposite sides of said slot, one of said plates having a pair of recessed portions facing said lateral grooves, respectively, said guide walls having a pair of retaining surfaces respectively engageable with said abutment surfaces of said legs to interlock said male and female members, and (2) a pair of cantilevered resilient arms having at distal ends thereof a pair of actuating lugs extending toward each other and engageable with said legs to bring said abutment surfaces out of interlocking engagement with said retaining surfaces, said actuating lugs being disposed respectively in said lateral grooves and having a pair of stop fingers projecting therefrom into said recessed portions of said one plate.
