Abstract
A coupling device provides a quick-release coupling of hose-like or tubular pipes to a connecting part at an outlet for a pressurized fluid. The connecting part has a locating face against which the end face of a flange positioned at the end of the pipe can be pressed by means of clamping screws. A sealing element is held between the flange and locating face. The clamping screws are anchored in the connecting part. The locating face of the connecting part is embodied by the base of a recess surrounding the outlet. The flange, at the end of the pipe, is housed in the recess such that the edge of the recess secures the flange against radial displacement. The clamping screws directly cooperate with the face of the flange opposite the end face.
