A device for the non-positive fixing of a hub on a shaft consists of two coaxial sleeves, one of which is inserted into the bore of the hub and the other of which is slid onto the shaft, the outer sleeve having an outer circumference matched to the circumference of the bore and the inner sleeve having an inner circumference matched to the circumference of the shaft, and the inner circumference (12) of the outer sleeve and the outer circumference (11) of the inner sleeve having an eccentricity such that, in one annular position relative to one another, the two sleeves fit into one another fairly loosely and, in another angular position relative to one another, are jammed together with the outer sleeve expanded and the inner sleeve compressed, jamming the hub to the shaft. The sleeves are rotated relative to one another and wedged by the application of two spanners, e.g. on respective hexagon profiles at the end of each of the two sleeves. <IMAGE>
