Abstract
Abstract A light-weight type lock having a body assembly and a pair of detachable hasps which protrude from opposite ends of the body. The body is box-like in form with movably related cover and configured body, securable together by keylock operation. The hasp ends are captured between the inner body configuration and the outer body when locked in assembly. In particular embodiments the hasps may be flexible members such as chains, or may be rigid "U" shaped members, either entirely releasible from the body assembly or releasible at one end of the hasp, and the outer and inner body members may slide or may pivot relative to each other to secure and to release the hasps, providing either alternative or simultaneous hasp release.
