1. Closure guard for a bottle, comprising:
a first housing part and a second housing part, which are configured to non-releasably enclose an upper portion of the neck of the bottle to be secured, including the bottle closure, when in a securing state;
the first housing part and the second housing part being interconnected so as to be movable relative to one another and being transferable between the securing state and a release state, in which the closure guard can be released from the neck; and
a locking mechanism, which is associated with either the first housing part or the second housing part and configured to lock the first housing part and the second housing part in the securing state,
wherein the locking mechanism comprises a locking pin which engages with both the first housing part and the second housing part when in the securing state in order to fix said housing parts in place in their relative orientation, and which can be displaced, by means of an actuation element, out of engagement with at least one of the first housing part and the second housing part in order to allow the first housing part and the second housing part to be transferred to the release state, and
wherein the actuation element comprises an actuator which is formed at least in part by a shape-memory alloy and/or a piezoelectric element.
