A method for fastening convergent walls of prefabricated, self supported structures, such as those of dwelling modules of vehicles like caravans, auto caravans, motor homes, etc. The walls of such dwelling modules, for example of an auto caravan (1), consisting of boards (7,7') having along their edges a profile (8,8'). After arranging two boards (7,7') at a predetermined angle with said profiled sections parallel and approached, for connecting and fastening them to each other junction elements (2,3) are used that can engage with the profiled grooves (10,10') of the relative profiled sections (8,8'); by tightening each junction element (2,3) in the groove (10,10') the final structure is kept integral and self supported. Furthermore, the use of two section bars, inner and outer (4,5), which are locked rotationally through a spacer element (15,19), complete the assemblage of the whole structure. For application of doors and/or windows, two section bars (23,24) are provided that assembled to each other make the frame of the doors and/or windows same. <IMAGE>
