ABSTRACT:
A one piece molded thermoplastic, preferably polypropylene, high security seal for coin bags has a locking socket body from which a flag extends on one side and a rectangular flat elongated shackle extends on the opposite side via an intermediate flat member which has a tear band there across for selectively separating the member into two pieces to facilitate removal of the locked seal. The shackle has several locking circular segment teeth in two parallel linear arrays on opposite edges of the shackle adjacent to a tamper resistant flange at the member end. A locking sheet metal stamped insert has two sets of tangs defining two spaced tooth receiving openings in a socket locking cavity aligned with shackle receiving openings in the body. The body receives the insert transverse to the shackle insertion direction through a cavity side wall later sealed with a flap formed in the seal body. The locked shackle precludes removal of the insert should the side wall seal be tampered with. The locked shackle forms a closed loop passed through an aperture in the bag folded neck. A hook on the intermediate member forms a tear band tab and engages the bag neck in the seal locked condition.
