If a tensile force is then exerted axially in the rearward direction on the handle 30 or on the handle 31, which can have an axial stop for this purpose, then the latching elements 35 are guided past the latching projections 36 and the housing edge 37 via the latching chamfers directed to the rear, wherein the locking elements 35 dodge inwards. As a result, the small suction device 1 is unlocked and can be removed to the rear.
  • Fig. 9 shows a further step for removing the small sucker 1 from the enveloping body 41 of the Stielsaugerrahmens 40.
  • the small sucker 1 is unlocked and opposite to the in Fig. 8 shown moved further back.
  • the handle 31 is returned relative to the small vacuum cleaner 1 and the handle 30 back to the first position, for which a spring may be provided.
  • the closure sleeve 16 has returned to its forward position by the force of the spring 17 in which the inlet windows 15 are concealed.
  • the suction mouth 3 of the suction head 2 of the small suction device 1 is released.
  • the small vacuum cleaner 1 can now be readily removed and used as a hand-held vacuum cleaner, for example as a table vacuum cleaner.
  • the locking elements 35 When inserting the small sucker 1 in the enveloping body 41, the locking elements 35 are passed over the shallower forward locking bevels on the housing edge 37 and the locking projections 36 and engage behind the locking projections 36 a. By locking cam 33 will prevent unlocking.
