The system for defrosting the leading edge sheath of an air intake hood for a turboengine comprises a hot pressure air supply duct (60) and a protective shell (90) which are longitudinally rigid and rigidly fixed to the partition (5) of a caisson (10), wherein said protective shell (90) is slidable with respect to a sliding bearing (15) embodied in the partition (11) and said air supply duct (60) is connected to the protective shell (90) by an elastic wall (16) closing an insulating space (12) and enabling relative longitudinal movements to be carried out between the air supply duct (60) and the protective shell (90).
