A fluid line of thermoplastic material includes a first end section integral with a principal part of the fluid line which is at least partially undulated. A first holding rib engages behind at least one locking projection of a connecting ring. The ring engages behind a second holding rib on a second end section of the pipe. The first end section has an essentially conical initial section located adjacent the principal part of the fluid line. The initial section has an outer diameter which increases in a direction toward the free end of the first end section. The initial section is adjacent to an intermediate section whose outer diameter decreases from the greatest diameter of the initial section to the smallest diameter of a locking groove for the engagement of a first locking projection.

Fluid line

A heating device includes an electrical heat source for heating a fluid in a fluid line of a motor vehicle, and a heat conducting device which is in connection with the heat source. The heat conducting device is connected with a hose clamp for connecting the heat conducting device to the fluid line. The heat conducting device may include a metal strip, the one end of which is in contact with the heat source and the other end is connected to the clamp. This metal strip facilitates the heat transfer from the heat source through the clamp to the fluid line.
