Pluggable tube system for a vacuum cleaner

摘要

The system (1) has a coupling for detachable connection of a tube (2) to another tube (3), where the coupling has a guide element (4) and a lever button (5). The guide element is located outside a wall of the former tube. The lever button is supported in the guide element to move around a pivot axis (6). A mechanical connection between the tubes is produced by engagement of a catch projection (8) with a catch recess (10) of the latter tube. An electrically conductive connection between the tubes is produced with a spring element (7) in a catch position of the button.
