The invention relates to a vacuum cleaner dust bag with a rigid collar (11) having an inlet opening (12) for a spigot tube (15) disposed on the vacuum cleaner. The opening is covered by an elastic diaphragm (13) having an opening. To prevent the bag from coming loose from the spigot tube the opening of the bag has a large zone (12a) and a smaller zone (12b), which are coherent, so that the spigot tube (15) can be inserted through the large zone (12a) and the bag be displaced laterally so that a flange (16) on the spigot tube will engage with surrounding parts of the small zone (12b) ot the opening. The bag is moved to and retained in this position by the elastic diaphragm (13) whose opening (14) is disposed centrally relative to the zone (12b) of small extension. |
