Abstract: A security device for hindering the unauthorized opening of safes includes first and second, retractably cooperable longitudinal members. First and second lateral members are provided at respective outer ends of the longitudinal members. A locking mechanism locks the first longitudinal member to the second longitudinal member. A tension spring retractably biases the second longitudinal member into the first longitudinal member. The locking mechanism can include a clamping member swivellably attached to the first longitudinal member and containing a pawl member, while the second longitudinal member includes a sawtoothed element. The clamping member can then be swiveled, so as to push the second longitudinal member further into the first longitudinal member. A vernier arrangement may be included 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.
