摘要

On the somewhat rectangular grip (17) on an edge (18) running parallel to the longitudinal edge (18) of the closure part (11) a concave recess (19) is provided, which indicates the correct insertion position of the closure part. The grip part in the area of the edge (23) opposite to the recess (19) has a through hole (22). The distance of the edge (18) with the recess (129) from the central longitudinal axis of the closure part (11) is greater than that of the opposite edge (23) from the centre longitudinal axis. The closure part and the grip part are of one-piece construction. The closure part is a drawn profile part and the grip part is produced by a moulding or stamping process. USE/ADVANTAGE - A key produced from two separately prepared parts joined together by laser or electron beam welding.
