A buckle comprises a male member (1) having a tongue-shaped presser (2) having on its bottom side a pair of engaging legs (5, 5) each having on its inner side a stepped portion (8, 8) and a female member (10) in the form of a case having in its top wall a central aperture (11), the female member (10) having a pair of resilient arms (12, 12), one mounted on each side thereof, each resilient arm (12) extending from one end of the female member (10) and terminating in a free end portion (14) for resilient angular movement about its proximal end (13), each free end portion (14) having on its inner side a hook-shaped engaging means (16) adapted for engagement with the stepped portion (8) of the corresponding engaging leg (5) when the engaging legs (12, 12) are forced into the central aperture (11). The tongue-shaped presser (2) further has on its bottom side a pair of resilient pieces (6, 6). The free end portions (14, 14) further have on their respective inner sides abutment portions (18, 18) adapted to compress the distal portions (9, 9) of the resilient pieces (6, 6) against the resiliency thereof as the resilient arms (12, 12) are angularly moved in the direction to bring the hook-shaped engaging means (16) out of engagement with the stepped portion (8, 8) of the engaging legs (5, 5). |
