In order to improve a throttle flap valve having a ring-shaped, elastic seal element ( 4 ) that surrounds an axial opening, having a valve disk ( 6 ) disposed to rotate in the axial opening, crosswise to the axial direction, having means for turning the valve disk ( 6 ) between the open and the closed positions, to control a flow of fluid through the opening, having at least two valve housing parts ( 5 ) that surround the seal element ( 4 ) in ring shape, which surround two flanges ( 3 ) connected with an inflow and an outflow, whereby conical contact surfaces of the flanges ( 3 ) and/or the valve housing parts ( 5 ) work together in such a manner that the flanges ( 3 ) are pressed axially against the seal element ( 4 ), forming a seal, by means of the valve housing parts ( 5 ), in the assembled state ready for operation, with regard to detrimental effects of axial forces that act on the seal element ( 4 ), it is proposed that the flanges ( 3 ) are rigidly connected with a clamp pair ( 5 ), forming a positive lock, in each instance.
