A locking device of a steering column adjustable in at least one adjustment direction ( 46 ) comprises at least one locking part ( 20, 21 ) associated with the adjustment direction ( 46 ) or one of the adjustment directions, at least one counterlocking part ( 14, 15 ) associated with this adjustment direction ( 46 ) and an openable and closable tensioning arrangement, in the opened state of which first and second toothings ( 38, 39 ) of locking parts ( 20, 21 ) are spaced apart from first and second countertoothings ( 40, 41 ) of the counterlocking part ( 14, 15 ), and in the closed state of which the locking part ( 20, 21 ) and the counterlocking part ( 14, 15 ) engage each other's teeth. The planes ( 47, 48; 49, 50 ) of the tips of teeth ( 42, 43; 44, 45 ) of the first and second toothings ( 38, 39 ) or first and second countertoothings ( 40, 41 ) are disposed in a V shape relative to one another and between the teeth ( 42, 43; 44, 45 ) of the first and second toothing ( 38, 39 ) or the first and second countertoothing ( 40, 41 ) is present an offset (v) in the adjustment direction ( 46 ), which is a fraction of the distance (a) between successive teeth ( 42 to 45 ).
