The invention relates to a device for detecting the pinching and/or cutting of a resistive connection comprising two resistive inner faces (33, 34) which are opposite to one another and are normally insulated from one another and which come into contact during the pinching of the connection, detection taking place by the change in the value of a resistance bridge including the abovementioned faces. It is characterised in that it comprises two resistance bridges connected in parallel between a first terminal and a second terminal of a direct-voltage source, each bridge comprising, in series, a downline resistor (31, 32) connected to the first pole of the source, one of the resistive faces (33, 34) and an upline resistor (35, 36) connected to the second pole of the direct-current source, the upline resistance of either one of the bridges being at least higher than 10 times the resistance of the resistive faces, the upline resistors being of different values, the ratio of their resistance values being at least equal to a few units, in that a pinch detector (41) is connected to the terminal (37) common to the upline resistor of highest value (35) and to the corresponding face (33), and in that a cut detector (39) is connected to each of the terminals (37, 38) common to a face (33, 34) and to an upline resistor (35, 36). <IMAGE> |
