A burglar-proof device designed to be fixed on one surface of a receiving wall located in or proximate to at least part of the periphery of an opening panel such as a door or a shutter, includes an elongated tubular element (7, 25) having a support wall (8) urged to be supported on the receiving surface (5), at least a fixing member (12, 12a) passing through a passage provided in the support wall (8) of the elongated element and which is fixed on the opening panel (2), at least an elastic return member (15) arranged in the elongated element, and at least a movement sensor mounted in the elongated element and co-operating with the receiving wall, so that, when the elongated element is stressed to counter the elastic member and moves away from the receiving wall, the movement sensor is capable of delivering an electric signal.
A burglar-proof device which can be fixed to a receiving surface of a receiving wall situated in or in a vicinity of at least part of a periphery of an opening panel, characterized in that it comprises an elongate tubular element (7, 25) having a bearing wall (8) bearing against said receiving surface (5), at least one fastening member (12, 12a) which passes through a passage formed in said bearing wall (8) of the elongate element and which is fastened to said receiving wall (2), at least one elastic return member (15) placed in said elongate element and interposed between said fastening member and said bearing wall of the elongate element, and at least one displacement sensor (20) installed in said elongate element and collaborating with said receiving wall, so that when said elongate element is urged against the action of said elastic member and moves away from said receiving wall, said displacement sensor is able to deliver an electric signal.
