A coupling station for coupling an air duct to an airport of a cargo container which comprises a coupling member movable in the direction of airflow therethrough between extended and retracted positions and a closure plate for sealing the open end of the coupling member, the closure plate moving in a plane normal to the direction of extension and retraction of the coupling member, the closure plate moving in a plane normal to the direction of extension and retraction of the coupling member in a plane located between the extended and retracted positions. The coupling station may be provided with automatic control from a two-position switch which when moved into a first position from a second position retracts the coupling member, then moves the closure plate to the open position and finally extends the coupling member and when moved into the second position from the first position retracts the coupling member, then moves the closure plate into the closed position and finally extends the coupling member.
