According to the invention, strong adhesion of the layers to each other and simple formation of a strong and leakproof connection with bags or connectors made from polypropylene or polycarbonate during steam sterilisation is achieved by the first plastic material containing at least one polymer which is dimensionally stable at temperatures of .gtoreq.121.degree. C., while the second plastic material contains at least one polymer which is no longer dimensionally stable at temperatures of .gtoreq.121.degree. C. A layer C) (2) is optionally present, the plastic material of which contains at least one polymer which is dimensionally stable at temperatures of .gtoreq.121.degree. C. The invention can be used for medical purposes, in particular as a fluid line in dialysis, infusion or artificial feeding, primarily in connection with connectors or medical bags.
