<p>A security device for tagging a bottle has a body 10 defining a sleeve 11 into which part of the bottle neck and its closure are received. A housing 14 is defined to one side of the sleeve 11 and first and second catch members 26,27 are pivoted within the housing 14 for movement between free and locking positions. When in their locking positions, the catch members 26,27 project into the sleeve 11 to engage behind a shoulder on the bottle neck or the closure, to resist removal of the device. An operating member 18 is also pivoted to the housing 14 for movement between open and closed positions, springs 31,35 being arranged between the operating member 18 and the first and second catch members 26,27 to urge the catch members to their respective locking positions. A magnetically-releasable latch 49,54 is arranged to hold the operating member 18 in its closed position unless the latch member 49 is acted upon by an external magnetic field.</p> |
