<p>A thermoplastic molded socket (142) and locking device including two tandemly secured locking devices (120, 121) are secured together at respective opposite ends of a strap (124). The socket (142) has two locking cavities (144, 146) each having a separate locking device receiving opening (144, 146) for receiving a respective different one of the locking devices (120, 121). The free end-most locking device (121) and one of the device receiving openings (146) have complementary dimensions, e.g., a transverse width greater than that of the other locking device (120) and device receiving opening (144), so that the end most locking device (121) can be inserted into only the one larger receiving opening (146). A unique reference number (160, 166) is assigned each seal (110) and to each cavity (144, 146) so that the seal and cavity reference numbers (160, 166) together form a unique number to preclude tampering. The locking devices (120, 121) each comprise a locking member (131, 130) and pair of locking tangs (129, 128), each tang including a rearward facing projection (153) which engages a corresponding recess (100') in the mating locking member cavity. In a further embodiment, the socket (142) has apertures (96', 98') for receiving the tang tips (137) for providing visual evidence of tampering, the tangs displacing in the socket cavities (144, 146) while locked.</p> |
