Claim 0:
1. An anti-theft device, comprising:
a housing, which is configured to be displaceable mounted to an anti-theft box, which anti-theft box is configured to receive merchandise to be protected, the housing being further configured to selectively take a releasing position, in which the anti-theft box is transferable from a closed state into an opened state, and a locking position, in which the anti-theft box is not transferable from the closed state into the opened state;
a locking mechanism associated with the housing and having an unlocked state, in which the housing is displaceable from the locking position into the releasing position, and a locked state, in which the housing is not displaceable from the locking position into the releasing position; and
an ejector, which is displaceable mounted in the housing and configured to take a retracted position, which corresponds to the locking position of the housing, and an extended position, which corresponds to the releasing position of the housing,
wherein the ejector is configured to be transferable from the retracted position into the extended position, if the locking mechanism is in the unlocked state, and wherein the ejector is biased towards the extended position,
wherein the locking mechanism further comprises a release element, which is made at least in part of a shape-memory alloy and is configured to cause the locking mechanism to be transferred from the locked state to the unlocked state when the shape-memory alloy of the release element is in an excited state, and a slide, which is designed to be translatable mounted in the housing,
wherein the slide is configured to be operatively connected to the release element as well as to a locking button of the locking mechanism, wherein the locking mechanism is configured such that the locking button transitions from its operated position to its non-operated position if the shape-memory alloy of the release element is in its excited state.
