Overlapping ends of metal strap or the like are connected without the aid of an overlying supplemental seal or fastener by means of longitudinally spaced joints which form a one way interlocking relationship. An integral abutment means comprises juxtaposed protuberances, integral with the overlapping strap segments, which irreversibly override each other as the interlocking relationship is formed and present spaced stops which abut each other before a formed interlock can disengage when the overlapping strap segments are shifted relative to each other in an interlock disengaging direction. |
