ABSTRACT:
A security seal has a band mounting a protrusion at one end and a housing at the other end. The end of the protrusion may be first passed through apertures in a latch or closure and then may be inserted into, and held by gripping facilities within the housing. The portion of the protrusion extending away from the housing resides in the apertures and prevents operation of the latch or closure absent damage to or disintegration of the seal. Vibratory and oscillatory motion which occurs during shipping or handling of an item bearing the seal can cause the aperture walls to cut or saw through the protrusion, giving a false indication of tampering. A protective shroud is provided which surrounds the protrusion and is interposed between it and the apertures to prevent cutting or sawing of the protrusion.
