Abstract: 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 at least one first heating conductor (20a) that is surrounded by a first heating conductor insulation (21) insulating the heating conductor from the inner volume (11). The invention is characterized in that the first heating conductor insulation (21) insulating the heating conductor from the inner volume (11) is surrounded by a second heating conductor insulation (22).

Abstract: 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).

Abstract: A connecting arrangement connects an end of a fluid conduit to an assembly. The connecting arrangement includes a stub (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 stub (1) and a second opening (10) for fastening to the assembly. The stub (1) is inserted into the first opening (9) and connected to the flange (2) in a material-to-material manner. The flange (2) has in the region of the connection a groove (4) that extends in a circumferential direction.

Abstract: A system for connecting hose lines, including a plug-in connector (2) and an electric heating element (36), wherein the plug-in connector (2) has at least one first (4) and one second connection (6) which are connected to one another by a tube (8), and wherein at least one section of the tube (8) can be heated by the electric heating element (36). The electric heating element (36) is embedded into a clamping ring (10) having a gap (12). The tube (8) is pushed through the gap (12) of the clamping ring (10) in such a way that the clamping ring (10) reaches around at least one section of the tube (8) and bears against the tube (8).

Abstract: A heatable hose conduit system is provided for an arrangement for the aftertreatment of exhaust gas in an internal combustion engine. The arrangement introduces a liquid reduction agent into the exhaust gas of the engine. The heatable hose conduit system has hose conduits that conduct the liquid reduction agent and are arranged in pairs in close proximity to hose conduits that conduct heating water. At least one end of at least one pair of hose conduits (6, 7 or 8, 9) terminates at a common connecting block that has a plug member of a plug-and-socket connector. The liquid reduction agent is conducted via the connecting block into the interior of the unit (11) to be connected and the heating water is conducted through a throughflow channel (20) which has an outlet outside the unit (11).

Abstract: The invention relates to a holder (2) for a pipeline segment (1) which takes the form of a clamp (3, 4, 5) with at least two ends. The clamp fits around the pipeline segment (1) and is firmly attached thereto. At least two of the ends of the clamp, which is fitted around the pipeline under tensile stress, are firmly and permanently connected to each other with the aid of at least one clinching connection.
