Abstract
A security seal includes a molded one piece body and a cover disc. The body has a cylindrical chamber for receiving the disc. A locking recess is formed in the body in communication with the chamber and defined in part by a locking shoulder. The cover is secured to the body in the chamber to enclose the locking recess. The disc is separated from the body when enclosing the chamber. A rotatable arm is attached to an extension member extending from the body via a hinge. The free end of the arm has an arrow shaped locking element attached that engages the recess locking shoulder when inserted into the recess. The locking element has a resilient tang member that is compressed by the locking shoulder and which tang member returns to its acquiescent state when fully inserted into the recess thereby locking the tang member in the recess. The cover has posts that extend through mating bores in the body, the protruding ends of the posts are deformed to preclude withdrawal of the posts from the bores to thereby lock the cover to the body.
