In the case of a bathtub with an air bubble system, the air nozzle arrangement has to be simple to install and also exchangeable. For this purpose it is proposed to provide a feed-line fitting (10), which can be connected to a pipeline (4) via a connection stub (22) and has a passage stub (11) which is directed towards the opening in the tub wall and is provided with a surrounding collar (12) bearing against the outer tub wall, and, from the tub inside, to introduce a tubular nozzle piece (3) through the opening in the passage stub (11) of the feed-line fitting (10) and to join it firmly to the latter. The pipeline runs may be introduced pre-assembled with the feed-line fittings. <IMAGE>
