Claim Text:
1. A pipe configured to channel pressurized air into an aircraft, comprising: an inner tube; an outer tube that is essentially coaxial to the inner tube; an insulating material inserted between the inner tube and the outer tube and that is made of a heat-insulating and gas-porous material; a leak detection device arranged at least in part between the inner tube and the outer tube and in that at least at one end, the leak detection device held in position by the insulating material follows a concentric trajectory to the inner tube, said insulating material filling the space between the inner tube and the outer tube, the leak detection device comprising two leak detection elements, each leak detection element forming a concentric loop; and a ring with a number of circular openings distributed over a circumference of the ring between the end and the concentric trajectory of the detection device, the circular openings being a distance from an edge of the ring, the ring being inserted between the inner tube and the outer tube and that, in case of a leak, hot air flows in the direction of the leak detection device by passing through the openings of the ring.
