A locking device is presented for an adjustable steering column assembly for a motor vehicle, comprising an actuating element and a damping device. The damping device has a first damping element and a second damping element, wherein the first damping element is attached to the actuating element and the second damping element is attached to a frame part, wherein the first and/or second damping element relative to the other damping element are rotatably mounted. The first and the second damping element each have a coupling section, wherein the coupling sections are engaged at least over a partial section of a movement of the actuating element, and wherein a relative rotation between the two damping elements is damped by deformation of the first and/or second damping element and/or by friction, at least over a partial section of a movement of the actuating element.
