Abstract

For a heatable medium pipe having at least one pipe connector and heating element, wherein the heating element has a few wires, in particular one or two wires, wherein the wire(s) extend continuously along the medium pipe and along the at least one pipe connector. In a method for producing a heatable medium pipe, comprising the medium pipe, at least one pipe connector, a transition area between the medium pipe and the pipe connector, and at least one heating element, wherein the heating element has a few wires, in particular one or two wires, the medium pipe is pre-assembled with the at least one pipe connector, the wire or the few wires of the heating element are pre-assembled as a double-laid, one or two-part element or as an element connected to form a continuous part, the wire(s) are fastened on the outside of the pipe connector, transition area and medium pipe, and the ends of the wire(s) are guided into a feed-in connector for connecting to a current source or voltage source.
