A detachable fitting device for fitting a mechanical component endowed with a cylindrical hole onto a shaft of circular section, comprising an end collar (1) of said hole having a substantially elliptical seat (2) and a bush (8) equipped with an elastically deformable external side surface for the reception of said shaft and shaped to be engaged in said elliptical seat (2). The bush (8) presents a first size, measured along a straight line perpendicular to the axis of the same bush, inclusive between the minor (b) and major (a) diameters of the elliptical seat and a second size, measured along a straight line perpendicular to said bush axis, less than the minor diameter (b) of said elliptical seat (2). |
