<p>A security device for hindering the unauthorised opening of safes, in particular hotel safes, includes a first longitudinal member (10) and a second longitudinal member (12), the second longitudinal member being retractably co-operable with the first longitudinal member. First and second lateral members (14, 16), which are used to clamp the device against the side walls of a safe, are provided at respective outer ends of the first and second longitudinal members. A locking mechanism ((50, 112, 122, 124) locks the first longitudinal member to the second longitudinal member, so that the device is tightly clamped to the safe. A tension spring (60) biases the second longitudinal member so that it retracts into the first longitudinal member. Preferably also the locking mechanism includes a clamping member (112) swivellably attached to the first longitudinal member (10) and containing a pawl member (122), while the second longitudinal member includes a sawtoothed element (50). The clamping member can then be swivelled, so as to push the second longitudinal member (12) further into the first longitudinal member by means of the pawl member (122) acting against the teeth of the sawtoothed element (50). A vernier means (150, 166) may be included enabling the user to further tighten the lateral members against the walls of the safe. The device provides, firstly, a visible deterrent and, secondly, a physical barrier to would-be intruders, allowing a hotel guest peace of mind when valuables are left behind.</p> |
