A connecting arrangement for a medical system, having a first part including a plastic material that is dimensionally stable at a heat-treatment temperature and a second part including a plastic material that is not dimensionally stable at the heat-treatment temperature and thus tends to flow under a compressive force; in which the plastic materials do not contain any PVC or EVA. The connection is made by bringing the surfaces on the first and second parts together with subsequent heat-treatment under a compressive force, wherein the second plastic material tends to flow under the simultaneous effects of temperature and compressive force.

[ We claim:] [1.] A connecting arrangement for constituents of a medical system, comprising a first and a second separate part in which at least one section of a surface made of a first plastic material on the first separate part and at least one section of a surface made of a second plastic material on the second separate part are touching in a contact area that comprises at least sections of the surfaces of the first and second parts to form a firm and well-sealed connection with each other, in which the first plastic material contains at least one polymer which is dimensionally stable at a temperature of heat-treatment sufficient for sterilization, whereas the second plastic material is no longer dimensionally stable at the temperature of heat-treatment and tends to flow under a compressive force, and wherein the second separate part is a non-PVC tube with at least one connecting layer made of the second plastic material, wherein the second plastic material contains at least one polymer whose softening point is lower than or equal to the temperature of heat-treatment.
