Claim:
1. A prefabricated electrically heatable media line, comprising: at least one tubing part having an electrically heatable multi-layer pipe wall having an integrated electrically conductive device provided as a middle layer comprising an electrical conductor located between an inner layer and an outer layer of the tubing part and with at least one connection device at an end region of the tubing part for establishing a fluidic connection of the media line, wherein the connection device is attached on or to the end region of the tubing part by primary shaping and/or material bonding, wherein the middle layer of the tubing part includes a plastic material filled with at least one conductive component, wherein the middle layer has at least two electrical conductors, wherein the electrical conductors are coiled around the inner layer of the tubing part at a gradient (S) of 20 to 150 mm, so as to enable or facilitate the forming and bending of the tubing part, wherein the at least one conductive component is one or more of conductive carbon black, metal powder, and carbon nanotubes, wherein the connection device is heatable by the electrically conductive device without having any additional conductor or heater provided on or in the connection device, and wherein at least one connecting element extends from the electrically conductive device to the outside of the connection device.
