Connection piece for a vacuum cleaner dust filter bag

摘要

A connecting piece (2) for a dust filter bag has a thin flexible foil sliding element (29) on the outside of the connection in the plane of the opening (12) which bends back on engaging with the connecting supports on the bag. A platelike surface of a connecting piece (2) for a dust filter bag comprises a projecting sliding element (29) of thin flexible foil on the outside of the connection, at least in the insertion direction, arranged in the plane of the connection opening (12). This bends back on engaging with the connecting supports to the bag and slides under the bulge of the connecting piece to the free end.
