Plug-in connection between a hose nipple and a housing wall

摘要

The invention relates to a plug-in connection, which is protected against rotation, between a hose nipple and a housing wall. A flange of the hollow plug-in pin of the hose nipple has an end tooth system towards the housing wall, which tooth system interacts, such that it is protected against rotation in a positively-locking manner, with a mating tooth system on the rubber seal which holds the plug-in pin in a sealed manner and such that it is secured axially. For its part, the rubber seal is fixed to the housing such that it is protected against rotation, by means of a non-round, preferably oval construction of the opening and of an external contour of the rubber seal which is matched to the shape of the opening. Using the plug-in connection, the outlet direction of the hose nipple can be set and locked without having to provide a toothed rim on the housing wall.
