Abstract: A vacuum cleaner structure wherein a force transfer structure is provided for facilitated positioning of a locking post provided for resiliently releasably locking a pair of flow passage elements in the vacuum cleaner structure. The force transfer structure defines a large area for facilitated fingertip manipulation and indication to the user of the location of the locking structure. The force transfer structure may be selectively mounted to other structure carried by the flow passage element. In one form, the force transfer structure is mounted to the flow passage element by an annular collar and, in another form, the force transfer structure is mounted directly to the flow passage element by a securing element, such as a rivet.
