Abstract:
1. Method of fastening first and second thermoplastic parts of a motor vehicle, wherein the first part has a protuberance projecting from one side and the second part has an engagement surface, the method comprising the following steps: bringing the second part into contact with said side of the first part, the second part being designed so that the angle between a vector normal to the side of the first part and a vector normal to the engagement surface is small and so that the engagement surface is close to the protuberance, wherein the protuberance is a tongue or rib, and the protuberance is substantially perpendicular to the side of the first part, heating the protuberance, plastically deforming the protuberance towards the second part using a deformation means moving substantially parallel to the side of the first part, so that at least one end portion of the protuberance is in contact with the engagement surface.
