An aircraft wing coupling arrangement couples services to and/or from a wing component which is translationally extendible from the wing of an aircraft. A housing is provided for mounting on the wing and includes a first coupling member. A hollow telescopic assembly extends from the housing for connection at a distal end to the wing component and has a second coupling member at the distal end. The telescopic assembly is extendible between a retracted and an extended position. A service carrying conduit arrangement carries the services to and/or from the wing component and extends through the hollow telescopic assembly from the second coupling member to the first coupling member. The service carrying conduit arrangement is flexible to locate excess thereof in the housing when the hollow telescopic assembly is in the retracted position.
