Device for detecting and/or monitoring optically invisible objects

A device for detecting and/or monitoring optically invisible objects, this device being intended to be mounted on said objects and disposed substantially parallel to a general direction of said objects, this device including:

• at least one electrically or optically conductive linear element, the at least one linear element extending longitudinally,
• an insulating sheath covering the at least one linear element, the insulating sheath including at least a first face intended to be mounted on said objects, the first face extending substantially along a plane and including a first substantially flat portion, wherein the insulating sheath includes at least a second face opposite to the first face, the first and second faces being substantially parallel, wherein the second face includes a second substantially flat portion substantially parallel to the first substantially flat portion, wherein the at least one linear element extends between the first and second substantially flat portions, and is disposed substantially equidistant relative to the first and second substantially flat portions, and
• first attachment means arranged on the first face of the insulating sheath and arranged to cooperate with an outer surface of said objects, the first attachment means comprising a first series of longitudinal ridges and a second series of longitudinal ridges disposed respectively on either side of the first substantially flat portion.
