ABSTRACT:
Overlapping ends of metal strap, or the like, are aligned and connected without the aid of an overlying supplemental seal or fastener by means of an array of longitudinally spaced joints which form a one-way interlocking relationship. The joints comprise juxtaposed protuberances formed by slits in the strap ends, integral with the overlapping strap segments, which override each other as the interlocking relationship is formed. A protuberance in the array on one of the strap ends is formed to additionally function as an integral anti-disengagement stop. This protuberance has an upturned corner forming a protruding tongue which, upon shifting of the joined overlapping lengths of metal strap relative to each other in a direction tending to disengage the joints, abuts a portion of the protuberance in a corresponding slit of the other strap to provide a stop preventing disengagement.
