To connect a hub to a shaft, spaced inner and outer rings have conical surfaces formed thereon, the conical surfaces diverging towards the outer sides of the connection. A pair of intermediate clamp rings which have essentially matching (but possibly slightly smaller conical angles) conical surfaces are inserted between the inner and outer rings, one from each side. Screws pass through one of the clamp rings and bear against its outer face, and are threaded into the other clamp ring, to tighten the rings against each other, the inner and outer rings being formed with a central recess of dove-tailed cross-section, in which a ring-shaped metal disc is inserted having an outer surface substantially matching the dove-tailed conical surfaces of the inner and outer rings. The clamp ring against which the screw surfaces bear is additionally formed with threaded openings to permit screws to be threaded therein, to then bear against the metal ring when separation of the hub to shaft connection is desired.
