<p>A tie-type security seal is described that comprises a body ( 2 ) of thermoplastic material with a passage ( 7 ) therethrough, a metallic insert element ( 11 ) that is fixed in the passage and has at least one opening ( 15 ) aligned therewith, as well as a locking tooth ( 14 ). An elongated strip of thermoplastic material ( 4 ) is integral, at one end, with the body ( 2 ) and has another free end for insertion through the passage ( 7 ) in a first direction where it is locked by the tooth ( 14 ) against removal from the cavity in the opposite direction, the body and strip having been manufactured by a plastic injection operation. In accordance with the invention, the seal is not only highly secure against tampering, but can also easily be mass manufactured since the metallic insert element ( 11 ) is incorporated into the body of thermoplastic material ( 2 ) during the injection operation.</p> |
