Method for producing a clip-on fastening system and corresponding clip-on fastening system

Abstract

The invention relates to a method for producing a clip-on fastening system, whereby a fastening element serves as the base of the clip-on fastening system and is linked with a support in a non-positive manner. The fastening element serves to detachably fasten the support with a component, especially a seal, in a clip-on manner. The component is provided with a clip area which has a cross-sectional shape corresponding to the cross-sectional shape of the fastening element. According to the invention, the fastening element is pre-fabricated as a hardened continuous profile by way of an extrusion method while using a hard material. The pre-fabricated fastening element is glued onto the support, and the component is then clipped onto the fastening element by way of its clip area, thereby producing a detachable connection.
