Abstract
A pipe (50) that makes it possible to channel pressurized air into an aircraft, includes an inner tube (52), an outer tube (54) that is essentially coaxial to the inner tube (52), an insulating material (56) that is inserted between the two tubes (52, 54) and that is made of a heat-insulating and gas-porous material, and a leak detection device (70), characterized in that the leak detection device (70) is arranged at least in part between the inner tube (52) and the outer tube (54) and in that at least at one end (60), the detection device follows a concentric trajectory (84) to the inner tube (52).
