The present invention relates to an air inlet cowl (9) for a jet engine, the leading edge (16) of which is hollow and supplied with hot air for deicing by a pipe (10) and an injector (12). According to the invention, the pipe (10) and the connector (12A) to the injector (12) are enclosed in an internal casing (27) which isolates them from heat-sensitive structures (26). The volume (28) inside the internal casing (27) communicates, on the one hand, with the outside through an orifice (34) and, on the other hand, through an orifice (35) with the peripheral annular space (22) which surrounds the engine fan and which is equipped with a vent door (23).
