Abstract: A buckle is disclosed, particularly for use in conjunction with belts, straps and the like. The buckle includes two mating parts which lock together upon insertion of a male member into a female member. The male member is generally rectangular in shape and has a slotted end suitable for receiving a belt or strap. The body of the male member includes a projecting portion extending at an angle from the plane of the body. The projecting portion is capable of movement about its point of attachment to the body. The female member is generally rectangular, and includes a slot therein for receiving the male piece. The slot is defined by a pair of opposing surfaces which the projecting portion can snap behind upon insertion. An opening is provided in the female member to allow the user to apply pressure to the projecting portion and remove the male member therefrom. A lip is provided to prevent the projection from slipping. A second opening is provided in the female member for the insertion of a belt or strap.
