Abstract: The device serves to fasten the edge (7) of the cover (6) of the cushion constituting a seat back (5) to the outer flange of a channel (4) that is open towards the rear and that is provided at the edge of a plate (3) constituting framework for said cushion, the fastening device comprising a J-section member (9) attached to the edge of said cover. Said flange is firstly extended outwardly by a lateral gutter (10, 11) that is open in the opposite direction to the channel, and secondly it has a series of holes (12) punched out therein so as to form a corresponding number of tabs (13) extending parallel to the general plane of the plate, and towards the inside of the channel.
