The invention concerns a coupling system between an air chamber 11 and a terminal device 16 for ventilation connected to it, preferably a valve. The coupling system includes a separate connection collar 13, which can be positioned relative to a cell R of the air distribution chamber 11 in such a way that a tube part 13a2 extends from the connection collar 13 into air chamber 11. The connection collar 13 can alternately be placed in such a way that the tube part 13a2 extends from it into an inner chamber space O of air chamber 11, in which by said alternative position of connection collar 13 a wide installation zone is made possible for connection of terminal device 16 for ventilation, preferably a valve, with a connection tube 16a1 from this to the tube part 13a2 of connection collar 13. <IMAGE> |
