Abstract
The assembly nut (5) is prescrewed onto the bolt (4) fixed to the booster (1), the nut and its bolt being introduced through a first end zone of enlarged cross-section (9) of an orifice in the wall (3), after which the booster is moved relative to the wall (3), in order to bring the body of the bolt (4) into a second end zone (10) of the orifice of a cross-section corresponding to that of the bolt, the nut (5) then being screwed home against the wall in the assembly position thus obtained. Advantageously, the wall (3) has a projecting part (11) adjacent to the orifice between the first (9) and second (10) end zones of the latter, so that, by putting itself in the path of the nut (5), it opposes a tendency for the unit to come apart.
