The invention allows an accessory to be attached to bars (7). Clip assemblies run freely inside the C-shaped rails (1) of the accessory, and are made up of an operating shank (2) with two screw threads of opposite hand connecting jaws (5) via tapped nuts (3 and 4) articulated to the inside of these jaws. By turning the operating shank in a given direction, the jaws self-centre, successively coming into contact with the bar (7), gripping same tightly and becoming wedged in the rail, this effect being supplemented by a locking effect whereby the jaws become braced against the rail. Unlocking is performed by turning the operating shank in the opposite direction. This device applies in particular to the attachment of a carrying accessory such as a roof box, roof tent, rack or the like to the roof bars of a motor vehicle.
L'invention permet de fixer sur des barres 7 un accessoire. Des ensembles pinces circulent librement dans les rails 1 en C de l'accessoire, et sont composées d'une tige de commande 2 à deux filetages à pas contraires reliant des mâchoires 5 par l'intermédiaire de noix taraudées 3 et 4 s'articulant dans ces mâchoires. En tournant la tige de commande dans un sens déterminé, les mâchoires s'auto-centrent en venant successivement au contact de la barre 7, la serrent fortement puis se coincent dans le rail, cet effet se doublant d'un verrouillage par arc- boutement des mâchoires dans le rail. Le déverrouillage se fait en tournant la tige de commande en sens inverse. Ce dispositif s'applique notamment pour fixer un accessoire de portage tel que coffre de toit, tente de toit, galerie ou autre sur les barres de toit d'un véhicule automobile
