A variety of machine covers have previously been provided with tamper- indication seals which, while not excluding unauthorized entry into machine covers, control or controlled areas, at least make unauthorized entry evident by breaking of the seal. The present disclosure makes dual use of a common fastener having affixed to it a frangible, plastic hanger that will break if unauthorized entry is made. Fig. 1 illustrates the concepts involved. A fastener 1, which may be a threaded screw, a rivet, a snap-lock friction fastener or any of a variety of similar devices, is outfitted with an extension 2 of frangible plastic, such as nylon or the like, molded in the form of a T- shape and rigidly affixed to the end of the fastener 1.
