Abstract
A connection device between a suction pipe and a vacuum cleaning unit, the unit having a closing flap (5) displaceable between an open position and a closed position at the suction inlet of the unit by using a control member (11) as well as a component for locking the nozzle (20) to the suction unit. The suction unit is a vacuum cleaner having a dust bag (1), the closing flap (5) being arranged on the bag (1), and a control member (11) cooperating with the nozzle (20) by means of a cooperation device so that the locking of the nozzle (20) is possible as soon as the flap (5) is in its open position. Application to vacuum cleaners with disposable bags.
