The invention relates to a clamping device for an injection molding machine for plastics, including a fixed platen ( 11 ) which is connected to a moving platen ( 12 ) by means of a toggle mechanism ( 13 ). A hollow-shaft motor ( 7 ) is provided to cooperate with a spindle ( 21 ) for operating the toggle mechanism, wherein the hollow-shaft motor ( 7 ) is connected to the toggle mechanism ( 13 ). According to the invention, the spindle ( 21 ) is arranged in a rotationally fixed manner, the end of the spindle ( 21 ), facing the moving platen ( 12 ), is in engagement with the rotor ( 6 ) of the hollow-shaft motor ( 7 ), and the stator ( 4 ) of the hollow-shaft motor is connected with the toggle mechanism ( 13 ). Preferably, a spindle nut is fixed in the rotor ( 6 ) for engagement with the spindle ( 21 ), preferably in the form of a recirculating ball screw.
