摘要:
The invention relates to a heatable tube (1) for conducting fluid, gaseous and/or pasty media, comprising an outer wall (10) that encloses an inner volume (11), and a heating element (2) which is arranged inside the inner volume (11) and which includes a first heating conductor (20a) and a second heating conductor (20b). The heatable tube (1) is characterized in that the first heating conductor (20a) and the second heating conductor (20b) are connected to one another by a heating conductor connector (20c) so as to form a loop in such a way that one heating conductor (20a, 20b) acts as a feed conductor (20a, 20b) and the other heating conductor (20a, 20b) acts as a return conductor (20a, 20b).

The present invention relates to a connection device for connecting an end of a fluid conduit to a unit, in particular a motor vehicle unit, which has a flow opening (11) and is to be supplied with a fluid. The connection device comprises a sleeve (1) having a flow opening (11) for receiving the fluid conduit at one end of the flow opening (11) as well as a flange (2) having a first opening (9) for receiving the sleeve (1) and a second opening (10) for fastening to the unit. The sleeve (1) is inserted into the first opening (9) and connected to the flange (2) in a cohesive manner. The flange (2) has in the region of the cohesive connection a recess (4) that extends in the circumferential direction.

The invention relates to a device for the aftertreatment of exhaust gas in an internal combustion engine by the introduction of a liquid reduction agent into the exhaust gas of said engine. The device has hose lines that conduct the reduction agent and are arranged in pairs in close proximity to hose lines that conduct heating water. At least one end of at least one pair of hose lines (6, 7 or 8, 9) terminates at a common connection block that has a plug-in connector. The urea solution is conducted from the connection block into the interior of the assembly to be connected and the heating water is conducted through a flow conduit (20), which has an outlet outside the assembly.
