<p>An improved security sealing device comprises a pair of hingedly connected metal jaws of which one has a tongue insertable through a slot in the other. The slot has inward facing lips while the tongue has catch tabs which, after insertion of the tongue through the slot, move to positions on opposite sides of the tongue such that by engagement with the lips of the slot they thereafter prevent opening movement of the jaws. By this arrangement it is virtually impossible to manipulate the jaw locking parts without visibly damaging the sealing device.</p> |
