Abstract

A tubing for a fluid medium of motor vehicles, in particular for an aqueous urea solution, comprises a tube, at least one heating wire, and a plug arranged on a tube end of the tube. The plug has a plug shank and a housing which surrounds the tube end and the heating wire. The plug shank comprises a latching means, preferably a collar, for latching in a connector. The tube has an inner tube and a contact element, wherein the heating wire is arranged between the inner tube and the contact element. The contact element brings the heating wire into contact with the inner tube, and the housing partially surrounds the contact element. A first segment of the heating wire runs on the tube end between the contact element and the inner tube, wherein a second segment of the heating wire runs between the contact element and the housing.
