Claim Text:
1. A detecting element for a cable for detecting leaks of electrically nonconductive liquid, said detecting element comprising—at least one sensor means which includes at least one detection member, produced at least partially from a material which swells upon contact with said liquid and which is filled with electrically conductive particles, such that: the detection member is conductive when it is not contaminated by said nonconductive liquid and the detection member loses its conductivity when it swells under the effect of said liquid; the sensor means has the form of an elongated bundle with a proximal end and a distal end with respect to a management module and which comprises moreover at least two insulated conductive wires, referred to as detection wires, forming a bundle extending over the entire length of the detecting element and which are connected by one end, referred to as proximal end, to said management module and in that said detection member is connected to an electronic module, referred to as the management module, arranged in order to detect the presence of said liquid by recording a decrease in the conductivity of said detection member, said management module being arranged in order to: detect the presence of liquid by recording a reduction in the conductivity of said detection member by means of a connection at one distal end of said detection member with the distal end of one of the conductive detection wires referred to as return wire, and verify the continuity of the detecting element by recording the electrical continuity of a circuit established by connecting the distal end of the other conductive detection wire, referred to as continuity wire, with the distal end of said return wire.
