Claim Text:
1. A method of connecting parts relative to one another is provided, the method comprising the steps of providing a first part, the first part defining an opening and a cavity communicating with said opening; providing a second part, the second part comprising 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, and wherein said cavity has an undercut and a well-defined cavity volume, said cavity volume being delimited by cavity walls surrounding the cavity; causing energy to act on the second part until at least a part of the thermoplastic material is caused to liquefy and fill the cavity; and causing the thermoplastic material to re-solidify, thereby anchoring the second part in the first part, wherein the cavity walls delimiting the cavity volume are impermeable to the liquefied thermoplastic material.
