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.
