1. A retaining device for a threaded member, in particular for a nut, for retaining said threaded member while it undergoes an operation of screwing or unscrewing along a screw axis, or while it is in the screwed condition, the threaded member having a linking shape with respect to the rotations about the axis and bearing at least indirectly on a part to be tightened by screwing action, the device comprising: a body intended to be fastened to the part and equipped with an anti-rotation shape capable of preventing rotation of the threaded member with respect to the part while allowing a radial clearance between the threaded member and the body, said retaining device moreover comprising an intermediate element provided with:
a shape complementary to the linking shape, capable of producing a coupling opposing a relative rotation between the threaded member and the intermediate element; and
coupling means capable of producing, with the anti-rotation shape of the body a coupling with a radial clearance between the intermediate element and the body, the coupling means also configured for opposing a relative rotation between the intermediate element and the body.
