Described herein is a heated flow line for a fluid-feeding system of a motor vehicle, comprising: - a pipe (2) made of plastic material with positive temperature coefficient; and - at least one first electric wire (3) and one second electric wire (4) electrically associated to said pipe (2) in such a way as to generate, when subjected to an electric potential, an electric current within said pipe, in a part thereof without said electric wires, according to a direction from said first wire to said second wire, or vice versa. The flow line is characterized in that said first and second wires (3, 4) are arranged on the outer surface of said pipe (2) and in that it comprises a sheath (5) that coats at least part of said outer surface and presses said first and second wires (3, 4) against said surface.
