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

A crosspiece including two terminal surfaces () and a pipe () with a longitudinal axis () that is essentially perpendicular to the terminal surfaces (), includes two parts (), each having a terminal surface (), a first part () including at least one edge () that can be flattened against an edge () of the other part (), with the edges having shapes that immobilize the two parts in the direction of the longitudinal axis () that makes it possible to adjust the relative position of the two parts in such a way as to obtain a desired length between the terminal surfaces.

An aircraft includes a hose that makes it possible to channel the pressurized air that is used in a sleeve () that delimits an annular chamber with the hose, with the sleeve () including at least one opening () that is delimited by an edge () that makes it possible to link the annular chamber and the outside of the sleeve (), and a leak detection system that includes at least one loop (A) in the form of a threadlike element (), characterized in that it includes a connecting device that includes a ring () that is connected at at least one connecting point () with a loop (A), and a flexible wall that delimits a hose () for channeling the air that extends from the edge () of the opening () up to the ring ().
