Abstract: A quick-release buckle with a main body, a plate, and a strap. The main body has a frame and a release lever that rotates about a shaft. The plate has two parallel and longitudinal slots, and the strap passes through the slots in the plate. The frame has two parts that are separated by an angled wall that extends laterally across the frame width. The shaft is secured to the first part of the frame. The second part of the frame is configured to form a seat for receiving the plate. The second part of the frame has two side walls and a channel on an inside surface of each side wall adjacent to the angled wall. Each channel is parallel to the angled wall and at least as wide as the thickness of the plate. The two channels together are configured to receive the width of the plate.
