<p>A security device for deterring theft of an object from a retail store comprises a base member (10), cable means (2) for placement about the object, spool means (14) rotatably mounted on the base member (10), the cable means (2) being connected to the spool means (14) such that the cable means can be wound around said spool means (14) enabling said cable means (2) to be tightened around said object upon rotation of the spool means (14) with respect to the base member (10) in a tightening direction, and a ratchet and pawl mechanism (22,24) configurable between an active configuration wherein the spool means (14) is constrained for rotation only in said cable tightening direction, and an inactive configuration whereby the spool means (14) is free to rotate in both the cable tightening direction and an opposite, cable loosening direction.</p> |
