The invention relates to a shifting device for a motor vehicle transmission, comprising a first coupling component, a second coupling component rotatable about a transmission axis (A), an inner friction ring which has a conical surface on a radially outer face, an outer friction ring which has a conical surface on a radially inner face, and an intermediate friction ring which comprises a friction cone and is connected to the second coupling component for joint rotation with and for axial displacement with respect to the second coupling component, whilst the inner friction ring and the outer friction ring are connected to the first coupling component for joint rotation with and for axial displacement with respect to the first coupling component. The friction cone extends between the conical surfaces of the inner friction ring and outer friction ring, the coupling components being decoupled in the rotation direction in an axial starting position of the outer friction ring and being coupled in a frictional fit in the rotation direction in an axial frictional fit position of the outer friction ring. The intermediate friction ring has a C-shaped ring cross section extending peripherally in the circumferential direction, comprising a radially outer linear cone limb which forms the friction cone and comprises two substantially parallel conical friction surfaces, and comprising a radially inner linear axial limb which is integrally connected to the cone limb by a radial web.
