A tamper evident security seal includes a locking unit and a bolt with a groove at its shank locking portion, the groove for receiving a resilient locking ring attached to a lock body in a locking unit receiving the bolt in a locked state. The locking unit includes two housing portions one of which has a top wall, a bottom wall and a first upstanding segment of a circular cylinder side wall interconnected thereto may be of any color. The top wall has an aperture for receiving the bolt therethrough. A mating second housing portion has a second segment of a circular cylinder side wall, preferably white having ID indicia thereon, forms a circular cylindrical housing with the first housing portion and is captured between the top and bottom walls. A lock body first element is plastic and molded one piece with the second housing portion. A lock body second steel element mates with the first element forming a lock body with an annular channel in which the ring is positioned. The channel and ring generally form a conventional bolt locking arrangement. A plastic transparent cover, enclosing the two housing portions, is bonded to the bottom wall. A collar on the top wall has two slots for receiving mating anti-spin tabs on the bolt shank. |
