A coupling device connects a medical therapy device, such as a therapy cushion, to a supply device. The coupling device includes a coupling part connected to a double hose line and a counter-coupling complimentarily designed to attach to the coupling part and fitted on the supply device. The coupling device further includes a plurality of shut- off valves that, by step-wise movement between the coupling part and counter coupling, selectively open flow paths for supply of different amounts of fluid per unit of time. A supply device employing the coupling device is also described. |
