Clamping device, especially for a steering column, with a first ramp plate, which can rotate relative to a second ramp plate between a released position and a clamped position by changing a distance between the ramp plates is provided. The first ramp plate ( 2 ) and the second ramp plate ( 3 ) each have at least two lifting ramps ( 5, 6 ) arranged in the circumferential direction for roller bodies and at least one guiding recess, and more preferably two diagonal guiding recesses ( 9, 10 ), in the plane of the ramp plates ( 2, 3 ) for control elements. The lifting ramps ( 5, 6 ) and the guiding recesses ( 9, 10 ) of the first and the second ramp plate ( 2, 3 ) are arranged so that they operate in opposite directions relative to each other.
