Abstract: A buckle 1 comprises a male member 10 and a female member 20 for receiving and anchoring the male member. The male member 10 has a male member main body 11, a resiliently deformable insertion piece 15 formed on the male member main body, an anchor surface 18 formed on the insertion piece and an operating section 17 also formed on the insertion piece and adapted to resiliently deform the insertion piece. The female member 20 has a female member main body 21, an insertion hole 23 formed in the female member main body and adapted to receive the corresponding insertion piece of the male member inserted into it, anchor-holding surface 27 to be engaged with the anchor surface of the male member so as to hold the male member in the female member and an aperture 25 adapted to expose the operating section of the male member to the outside as the anchor-holding surface is engaged with the anchor surface.
