ABSTRACT:
A one-piece tamper-proof bundling strap comprised of a head-end portion defining an aperture therethrough, the head-end portion being integrally connected to an elongated narrow body portion, the aperture in the head-end portion corresponding generally to the cross-sectional configuration of the body portion. The head-end portion and the body portion have a locking means integrally associated therewith for preventing reverse movement of the body portion relative to the head-end portion when the body portion is looped upon itself and disposed within the aperture of the head-end portion. The locking means is comprised of a plurality of serrations oriented along a portion of the length of the body portion and a plurality of projecting teeth members disposed within said through-aperture adapted to lock against the serrations when the body portion is looped upon itself and drawn through the aperture in the head-end portion. The strap is a one-piece unit constructed of a single, preferably brittle material which will fracture when exposed to tampering forces.
