The portions are coupled to one of ends of a zigzag channel of the latter section by a part laterally opening in the former portion rectilinear to neighboring of an inlet orifice of a circuit elastically restraining a rod to the former portion and to another end by a part elastically releasing the rod to the former section. Independent claims are also included for the following: (1) a system for fixing a backrest to a base of a seat (2) a method for mounting a backrest to a base of a seat.
