A body portion (1) of the lock is formed by a link member (3) of the ornamental chain, a hinge link (4) of which is replaced with a shaped combination of a hinge and a locking bow (2', 2), whereby the lock differs in shape from the other link members of the chain as little as possible. In addition, a point portion of the bow spring (2) is in the locking position protected against any outside contacts. Being integral in construction, the lock enables chains to be shortened without any laborous soldering step, because even a shortened chain can be connected to the bow spring (2). When chains are joined together, the bow spring portion (2) of the lock (1) is scarcely noticeable in most chain types. The bow-spring lock (1) is also as a separate lock adaptable to all chain types by the use of linking rings. <IMAGE> |
