The locking tab includes a pivot extension extending radially outward from the outer surface of the second vacuum cleaner accessory, and a latch pivotably connected to the pivot extension. The latch includes a finger engagement portion and a latching portion located on opposite sides of the pivot extension. The latching portion includes a latch tooth that extends from a bottom surface of the latching portion. The latch tooth is positioned to engage the teeth upon insertion of the inner attachment tube into the outer attachment tube to secure the first vacuum cleaner accessory to the second vacuum cleaner accessory.
