A steering column may include an inner casing tube in which a steering spindle is rotatably mounted, an outer casing unit that retains the inner casing tube, and a clamping device that secures the outer casing unit relative to the inner casing tube in a fixing position and enables adjustment in an enabling position. The clamping device comprises an arresting element supported longitudinally on the outer casing unit and, in the fixing position, is connected in a longitudinally non-displaceable manner to an engagement element connected to the inner casing tube and, in the enabling position, is released from the engagement element and enables movement of the inner casing tube relative to the outer casing unit in a longitudinal direction. A plastically-deformable energy absorption device, which includes at least two energy absorption elements and a coupling means, may couple the inner casing tube and the outer casing unit.
