<p>Security device (10) comprising a clasping member (100) for enclosing an object to be secured, the clasping member comprising a conducting member, a locking member (200) connected to the clasping member, such that the locking member (100) and the clasping member (200) form a loop, the locking member in turn comprising, a gear member (290) comprising a protruding profile (292), the gear member (290) extending in a first plane with a protruding profile (292) raised from the first plane, a manoeuvring member (220) extending in a second plane parallel to the first plane, the manoeuvring member (220) being rotatable relative the gear member (290) and comprising a latch member (231, 232) biased towards the first plane arranged to engage the gear member (290), such that rotation of the manoeuvring member (220) in one direction causes a narrowing of the loop whereas rotation in the opposite direction causing a widening of the loop. Rotation in the opposite direction is prevented through the engagement of the latch member (231, 232) with the protruding profile (292). A pulling of the clasping member (100) in the locked position causes a movement of a movable element (245, 246) towards an elastic element (247, 248) deforming the latter thereby interrupting the alarm circuit of the security device (10) and activating an alarm signal.</p> |
