<p>EAS marker (181), in one embodiment, comprises a self-lockable loop fastener. The self-lockable loop fastener comprises an elongated strap (83) having a first end (84-1) and a second end (84-2), the second end (84-2) being provided with a plurality of teeth (91). The self-lockable loop fastener also comprises a paddle (93) disposed at the first end of the strap. The paddle includes a recess (95) and a locking head (85). The second end of the strap is insertable into, but not through, the locking head (85), the locking head (85) having a tang (87) for lockably engaging the teeth (91) in such a way as to prevent withdrawal of the strap from the locking head and thereby forming a locked loop of fixed size. The EAS marker (81) also includes a resonator (101) disposed within the recess (95) of the paddle (93) for emitting, when armed, a response signal in response to an interrogation signal transmitted by an EAS system, a biasing element (97) disposed within the recess (95) and positioned relative to the resonator (101) so that, when the biasing element (97) is magnetized, the resonator (101) is armed.</p> |
