1. A urea feed or return line that comprises:
a coupling connected to a urea tank that includes a passage for urea and a first heating filament, at least one part of which extends freely inside the passage for the urea, the at least one part having the shape of a loop or a spiral capable of also extending at least partly into the urea tank and/or into a tube attached to the urea tank; and a second heating filament inside the line that is connected in series or in parallel with the first heating filament, wherein the coupling is connected to a tube molded as one part with a base that seals an opening in a wall of the urea tank and that integrates at least one active storage and/or injection component.
