A coupling of a suction nozzle, with a connector of a suction hose of a vacuum cleaner being rotatably mounted in the coupling, whereby the connector, on an end thereof that faces the suction nozzle, is provided with a larger diameter flange that for the axial fixation and rotatable mounting of the connector extends into an undercut of a cylindrical receiving opening of the coupling. A sleeve is provided between the connector and the receiving opening of the coupling. Cooperating arresting means are provided on the sleeve and the coupling for connecting the same, whereby the sleeve, together with the coupling, form the undercut thereof.

Suction nozzle coupling having rotatably mounted therein a connector for

A cleaning apparatus, especially a suction nozzle, for a vacuum cleaner. The apparatus has a joint pan connected with an apparatus housing, and a joint head connected with an apparatus connecting piece for a handle of the vacuum cleaner. The joint parts are parts of a joint, especially a tilting joint, and delimit a gap of movement of the joint. At least one of the joint parts is a part which can be detached from the apparatus part respectively associated therewith, which detachable part is provided at least partially with a fiber packing which projects into the gap of movement. The fiber packing includes closely packed fibers which are arranged at least substantially at right angles on an associated supporting surface of the joint part.
