The female member includes a cylinder body for receiving the main body therein, a projecting portion formed on an outer periphery of the cylinder body at one end thereof, and protruding portions formed at the other end thereof. A first engaging portion is formed on an outer surface of a main body of the male member or an inner surface of the cylinder body, and a second engaging portion engaging the first engaging portion is formed on the inner surface or the outer surface. The second engaging portion has two engaging sections and a smooth surface portion interposed therebetween.
