ABSTRACT:
A molded thermoplastic body is formed with a rectangular cavity. A molded thermoplastic insert is welded to the body in the cavity and has a top cross member, a stem member and a bottom member. The stem member has a plurality of molded fingers cantilevered on opposing sides inclined relative to the stem member longitudinal axis in one embodiment. The stem member forms the cavity into two channels. A wire shackle which may be round or square in section, a wire or molded plastic, is U-shaped with two legs. One leg is formed with notches to receive the tips of the fingers in one channel and the other leg is formed with a reversibly bent barb which engages the fingers in the other channel on the opposite side of the cavity. The bottom member limits the insertion depth of the legs. The notches and barb engage the fingers and lock the shackle to the body. When the shackle is severed, and the notched leg rotated to disengage the notches in the leg from the fingers to remove the leg from the body, the other leg with the barb can not be rotated and readily removed to thereby provide evidence of tampering. Other embodiments are disclosed including providing the notched leg with squared sides and an entrance opening into the corresponding channel that is square to preclude rotation of the notched leg and shackles of different configurations.
