Abstract

a. Dispositif pour serrer un écrou vissé sur un goujon fileté; b. Dispositif caractérisé en ce que la douille comporte à son extrémité voisine de la pièce, une fente traversant radialement la douille, et s'étendant dans la direction longitudinale de cette douille, pour permettre de serrer l'écrou d'un angle qui correspond à une force de serrage prédéterminée, ainsi qu'une cavité, réalisée dans la douille, cette cavité étant dirigée vers la surface d'appui de la pièceat. Device for tightening a screwed nut on a threaded stud; b. Device characterized in that the sleeve comprises at its end adjacent to the part, a slot passing radially through the sleeve, and extending in the longitudinal direction of this sleeve, to enable the nut to be tightened at an angle which corresponds to a predetermined clamping force, as well as a cavity, made in the sleeve, this cavity being directed towards the bearing surface of the part
