Abstract
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.
