摘要： The invention relates to a reductant supply system for a waste gas cleaning catalyst of an internal combustion engine, in particular of a vehicle, comprising a reductant tank (3) for the holding of reductant, a connection line (4, 5) in order to convey reductant from the reductant tank (3) to a waste gas cleaning catalyst (2), and a pump (6) to pump reductant from the reductant tank (3) to the catalyst (2). According to the invention it is provided that at least one section of the connection line (4, 5) is configured as a corrosion-resistant metal pipe being provided with electrical terminal lugs (10, 11, 12, 13) in order to convey an electrical hating current through the connection line (4, 5) for the defrosting of reductant. The invention relates further to a heating unit for such a supply system, comprising a corrosion-resistant metal pipe (4) for immersion into the solution, which pipe can be attached to the pump (6) as intake pipe for the conveyance of the defrosted solution, and at which are affixed terminal lugs (10, 11) for the conveyance of a heating current through the metal pipe (4), which current heats up the metal pipe (4) for the defrosting of solution.
