ABSTRACT:
EAS marker, in one embodiment, comprises a self-lockable loop fastener. The self-lockable loop fastener comprises an elongated strap having a first end and a second end, the second end being provided with a plurality of teeth. The self-lockable loop fastener also comprises a paddle disposed at the first end of the strap. The paddle includes a recess and a locking head. The second end of the strap is insertable into, but not through, the locking head, the locking head having a tang for lockably engaging the teeth 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 also includes a resonator disposed within the recess of the paddle for emitting, when armed, a response signal in response to an interrogation signal transmitted by an EAS system, a biasing element disposed within the recess and positioned relative to the resonator so that, when the biasing element is magnetized, the resonator is armed; a separator disposed within the recess between the resonator and the biasing element for physically separating the resonator and the biasing element; and a cover secured to the paddle to encapsulate the resonator, the separator and the biasing element within the recess and to prevent access to and tampering with the tang and the locking head.
