1. An aircraft wing comprising:
a wing leading edge;
a cut-out opening in the wing leading edge;
a telescopic tube extendable through the cut-out opening and connected to an internal duct of the wing leading edge to establish fluid communication with heated air associated with an aircraft anti-icing system, wherein the telescopic tube is moveable between retracted and extended conditions in response to a wing leading edge slat being moved between slat retraction and deployment positions, respectively;
a cover assembly comprising a cover member operatively connected to the telescopic tube to close the cut-out opening and allow synchronous movement of the cover member with the telescopic tube in response to the telescopic tube being moved between the retracted and extended conditions thereof; and
an articulated connection between the cover member and the telescopic tube.
