Abstract

The assembly nut (6) is prescrewed onto the bolt (5) so as to be up against a tubular spacer (15); the bolt, together with its nut and its spacer, is introduced through a first end zone of enlarged cross-section of an elongate orifice made in the fixed wall (4), after which the booster is moved relative to the wall in order to bring the spacer (15) into a second end zone of the orifice in the wall, of a cross-section corresponding to that of the spacer, and then a plate (18) likewise having an elongate orifice with two end zones of different cross-sections is interposed between the wall (4) and the nut (6), the plate being moved in order to place the spacer (15) in the end zone of corresponding cross-section (22) of the orifice in the plate, this movement producing, between the wall (8) and the nut (6), a wedge effect attributable to an edge of variable thickness (24) of the orifice in the plate (18).
