A fluid supply conduit configured to pass through a constrained environment, comprising:
- at least one oblong section tube having a substantially oval section, and
- a plurality of external stiffeners of hollowed out shape with a U-shaped section adapted to encircle the oval section tube over a portion of its section, the plurality of external stiffeners being distributed over a length of said tube, two successive external stiffeners being positioned head to tail around the oblong section tube such that a pair of successive stiffeners forms an alternating banding around said tube.
