A hose for an aircraft parked at a remote location from a source of pre-conditioned air through which the pre-conditioned air, under pressure, is delivered through the hose, wherein the hose construction uses to advantage a length portion having a bellows, in that the bellows folds are constrained by an internal strap from longitudinal expansion and thus are not "blown out" by the pressure air and yet, retain degrees of rotation and contraction.
