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.

Abstract: The invention relates to a manually operated fixing clip for joining together removably and so that they can pivot two elements one of which carries the clip and the other a rod forming a pivot pin. The clip has a flexible lip forming, together with another lip, an elastic pinching slit for the entrance of the rod into a housing. A movable bar connected to the clip by elastic tags is placed between two lips either to move them apart sufficiently to allow the rod to leave, or to block the flexible lip in order to prevent the rod from leaving, depending on the embodiment.
