Abstract: A clasp for an article of jewelry comprises an elongated rigid ring element, which may be of generally rectangular configuration, and an elongated rigid hook element defining a generally U-shaped part-receiving chamber having its base at the front of the hook element. The ring element has four parts or legs defining together an aperture which may be generally rectangular in configuration, the front part being of reduced thickness with the top surface thereof disposed below the plane of the top surfaces of the side parts. The two elements, when assembled together to form the clasp, have the front part of the ring element disposed in the part-receiving chamber of the hook element, a major portion of the aperture visible from the top of the clasp, and the top surface of the front of the ring element in substantially the same plane as the top surface of the body portion of the hook element.
