The heating cable comprises one or more electrically resistant wires surrounded by an electrically insulating layer, and is shaped as a snaking line and covered, between two consecutive extremities 3a, 3b, with a straight segment 4 of a profiled member made from a rigid material with high bending resistance and high hardness, each end of which is set slightly back from the adjacent extremity 3a or 3b. Each segment 4 is fixed at one point of a longitudinal lace or strap 10 so that the angle between two adjacent straight segments 2 is constant. The transverse section of the profiled member is in the shape of an inverted U, the ends of the branches 5, 6 of the U being slightly toed in. <IMAGE>
