There is disclosed an adjusting device for a valve, especially a pressure control valve, comprising an axially displaceable control member on which a control spring acting on a valve body of the valve is supported. The control member is in rotational engagement with a catch connected to a handle for adjusting the control spring biasing. In accordance with the invention, the rotatable handle is connected to the catch such that first a radially projecting locking member is inserted in a recess in axial direction and subsequently is brought into an axial locking position by a relative displacement so as to lock the handle in axial direction with the catch.
