Abstract: A strap, which can be a strip of metal, is provided for forming a tight loop about an object and for forming a sealless strap connection between overlapping strap portions. The strap has first and second oppositely facing surfaces and two connecting regions spaced apart lengthwise on the strap. Each connecting region has at least one joint element for engaging a corresponding joint element on the other connecting region to connect the regions together upon displacement of the connecting regions lengthwise in opposite directions tending to increase the loop size. An engaging member projects from the strap first surface at one of the connecting regions. A cavity is defined in the strap at the other of the connecting regions and opens to the strap second surface for receiving the engaging member. The cavity is defined at one end by an abutment surface for being engaged by the engaging member.
