The insertion section includes a middle leg, and elastic legs with engaging projections disposed at both sides of the middle leg. The female buckle includes engaging windows engaging the engaging projections of the elastic legs. The elastic legs are elastically deformed inwardly upon insertion operation of the insertion section, and at a predetermined position, the engaging projections enter into the engaging windows elastically. Also, the female buckle includes a pair of dividing plate portions for guiding and holding the middle leg therebetween, and the dividing plate portions extend between inner walls of the female buckle which face each other.
