The present invention relates to an air inlet cowl (9) for a jet engine, especially for an aircraft. According to the invention, the diffuser (12) of hot air for de-icing, arranged in the hollow leading edge (16) of the cowl (9) is in the form of a polygonal ring and is fixed by elastic support tabs (24) each equipped with a ball joint (25) holding a straight portion (22) of the polygonal ring.


[ What is claimed is:] [1.] An air inlet cowl (9) for a jet engine (1), especially for an aircraft, said air inlet cowl (9) being equipped with means for de-icing its leading edge (16) and comprising, for this purpose:a hollow leading edge (16) delimiting an annular internal peripheral chamber (21) which is closed by an internal partition (20) and equipped with at least one orifice (18) placing said internal chamber (21) in communication with the outside; anda pipe (10) which can be connected, at its rear end away from said leading edge (16), to a pressu...
