ABSTRACT:
The invention relates to a vacuum cleaner nozzle that is provided with a latching device between the attachment stub and the nozzle housing. These elements are latched together in a defined swivelling range in such a way that they perform a common synchronized swivelling movement. The elements can be unlatched again by overcoming the action of a spring-loaded latching bolt.
