There is disclosed a quick-connect-disconnect coupling for attaching a flexible dirt-receiving bag to the handle of an upright vacuum cleaner. The coupling includes first and second coupling members, respectively, which are rigidly attached to the handle and to the bag, with the second member rigidly supporting at least a major portion of a bag-supporting casing as a cantilever. The first coupling member defines a pocket in which there is provided a fixed member and a movable member. The movable member is biased toward the fixed member, and the second coupling member is adapted to be releasably inserted between the fixed and movable members. The movable and fixed members cooperate with the second coupling member to define a one-way ratchet which is releasable upon movement of the movable member away from the fixed member. |
