ABSTRACT:
A security seal has an elongated flexible strap integral with a housing at one end. The other end of the strap can be moved through a passageway in the housing to form the strap into a closed loop. Facilities in the housing and on one surface of the strap permit movement of the strap out of the passageway and prevent reverse movement of the strap if the strap is properly inserted without a half-twist and into the proper end of the passageway. These facilities are ineffective to prevent reverse movement if the strap is improperly inserted. The seal is improved by forming a groove longitudinally in the passageway. A surface feature on the other surface of the strap is conformally received in the groove when the strap is properly inserted into the passageway without twisting. If the strap is improperly inserted, the passageway interferes with and applies force to the surface feature. This force discolors or deforms the surface feature to provide a visual indication of improper insertion.
