Abstract

The invention relates to an intrusion preventing apparatus for fences (1, 2) comprising one or more cables (3) composed of a fiber optic bundle (103) and an outer protective sheath (203), which longitudinally subtend a perimeter to be protected and are supported at a plurality of vertical spaced posts (4) and wherein, at least at some of said posts (4), means (8, 9) are provided for deforming the cables (3), which may be moved from an idle position to an operating cable (3) deforming position in which an optical signal is attenuated below a threshold value, which means (8, 9) are operated as the tension of the cable (3) is increased. According to the invention, said deforming means are a pair of clamping jaws (8, 9) facing toward each other on opposite sides of the cable (3) and freely pivoting on pins (10) along the axis of the cable (3), which jaws, in the idle position, engage the outer sheath (203) of the cable (3) with a predetermined force without deforming it whereas, as the tension of the cable (3) increases, they are urged by the cable (3) into an arc-shaped pivotal motion, thereby causing the cable (3) to be pinched. The invention further addresses tamper preventing means (12, 13) for the apparatus. Said deforming and/or pinching means are disposed in a housing which is formed by two separable parts and has tamper indicating means composed of second fiber optic cable deforming and/or pinching means.
