Abstract
A buckle comprises a male member and a female member. The male member is provided with an insertion portion adapted to be inserted into the female member and an insertion hole formed inside of the insertion portion. The female member is provided with a recess in which the insertion portion is to be fitted, and an accommodating portion adapted to communicate with the insertion hole. The accommodating portion is provided therein with an engaging piece swingable in an inserting direction to the insertion hole. The engaging piece is provided with an engaging portion which is to be inserted through the insertion hole. The insertion hole of the male member is formed with a locking surface against which the engaging portion is adapted to abut. The accommodating portion is provided with a pair of receiving portions located at opposite sides of the recess for supporting a pair of abutment portions of the engaging portion, and is adapted to be located on opposite sides of the locking surface in an engaged state of the buckle. Therefore, the buckle has a high engaging force between the male member and the female member, and these members can not be disengaged from each other unintentionally even if tensile force is applied to the buckle.
