Coupling device for connection of fire place to chimney of pressure-tight exhaust system in building, has clamping device for clamping-type connection of flange with pipe connection piece and acting in axial direction of axis of piece

摘要

The device has a plastic coupling adapter (1) to which a pipe connection piece (2a) is coupled, where the pipe connection is formed at a ceramic molded part (2) i.e. angular ceramic nozzle. The adapter has a coupling flange (1f) resting on a front side of the pipe connection piece under interconnection of a sealing element (11) i.e. O-ring, in a coupling position. A clamping device (14) is provided for clamping-type connection of the flange with the pipe connection piece, and acts in an axial direction of an axis of the pipe connection piece in the coupling position.
