Abstract
EAS marker, in one embodiment, comprises a self-lockable loop fastener.

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 re…
