Abstract
A method of connecting parts relative to one another includes the steps of providing a first part, the first part having an opening; providing a second part, the second part having thermoplastic material in a solid state; arranging the first part and the second part relative to one another, so that the second part reaches into the opening, while a volume with an undercut is defined in the opening; causing a mechanical pressure and mechanical energy to act on the second part until at least a part of the thermoplastic material is caused to liquefy and to fill the volume; and causing the thermoplastic material to re-solidify, thereby anchoring the second part in the first part.
