Improvements introduced in friction couplings, especially for gear changes in boats, with a sleeve holder fixedly mounted on one of the parts to be coupled and an axially displaceable friction ring with, preferably, conical friction surface driven by a clutch sleeve, whose friction surface cooperates with a friction surface disposed on the other part of the coupling, characterized, because for the generation of the clutch force, the axially displaceable friction ring is rotatable in a relative and limited manner, and provided, on the front surface opposite the friction surface, cuneiform surfaces, formed, with respect to the front plane thereof, inclined in the direction of the main axis, being furthermore arranged in cavities of the sleeve carrier on radial axes, and same level of sleeve carrier, pressure rollers that in case of relative rotation make a stop with the super cuneiform fibers of the friction ring.
