<p>A fastener formed by an elongated member with an apertured tip (16), such as a filamentary string (15) that is attached to a bidirectional locking head (11) with longitudinally opposed openings (C1, C2). The elongated member is inserted into either of the opposed openings (C1, C2) of the head (11), where it is engaged and locked in place by an internal, at least partially circumferentially ring (11r). Once the apertured tip (16) is inserted into the locking head (11), it remains in its locking position even if the filamentary string (15) becomes separated from it as a result, for example, of pilferage.</p> |
