ABSTRACT:
A tamper-indicating seal of the type having a bolt retained in a lock body, wherein the lock body is surrounded by a shroud of frangible, brittle material and provided with a grooved outer surface and flanged entrance way for receiving and surrounding the bolt end, whereby the shroud is easily fractured, thus providing visual indication of tampering. Visual detection of tampering may be enhanced by a coating applied to the outer surface of the shroud. A surface feature on the between its point of entry into the lock body and its point of entry into the flange is in interfering relationship with a surface feature within the flange, so that an attempted removal of the lock body from the shroud is indicated by cracking, chipping, or fracturing of the flange or the shroud.
