The gas guiding device is provided with connections for detachably and sealingly linking with a gas feed line and a gas discharge line. Ends of every pipe are separately connected to one and the same connecting head that has a gas inlet and a gas outlet opening the axially aligned therewith. The end of the gas feed line and the end of the gas discharge line are opposite each other and can be displaced along with the gas inlet opening and/or the gas outlet opening while sealingly connected.
