The hose (1) has two layers, in which the layer facing a dual pipeline (2) consists of plastic fleece (4) i.e. polyester fiber fleece. The layer that is turned away from the pipeline consists of another plastic fleece (3). A neck (6) is provided between two pipes (2a, 2b) for insulating casing of the dual-pipe line comprising parallel running pipes. An area of the plastic fleece (4) contacts another area of the plastic fleece (4) in the neck. The areas are connected with each other in a fixed manner. A layer is provided as an outer layer (5) at an outer side of the plastic fleece (3). |
