Abstract (en)

The present invention relates to a method for fixing a coupling flange (11) of the connecting crosspieces between the uprights of a scaffold to the tube (10) of the upright itself, comprising the steps of fitting said flange (11) on said tube (10) and radially deforming said tube (10) so as to obtain two locking edges or rings (20,21) suitable for clamping the flange (11) thereinbetween. The fixing method proposed allows preventing any welding operation between the flange (11) and the upright (10).
