<p>The invention concerns a coupling device for a detachable connection of a suction hose to the inlet opening in a vacuum cleaner housing, said inlet opening including a socket for receiving a tube connecting piece mounted on the suction hose, said connecting piece including latch means that are realisably connected to the socket and sealing means interacting with the socket, wherein the connecting piece includes a plurality of symmetrically arranged resilient latches and that said latches are realisably connected to openings that are formed in an external wall member that is integrally formed on the housing. Hereby, a snap fit connection between the suction hose and the tank element of the housing is provided where the connecting piece of the hose connects to the housing without extra connection parts. Thus, the number of parts involved in a coupling device according to the invention is reduced making the coupling device cheaper and quicker to manufacture. <IMAGE></p> |
