The fixing device is for the motor housing (10) that has an annular skirt (14) that ensures there is a seal between the motor housing (10) and a wall (5) delimiting the central opening of the fan box. The fixing (15,17) is of the bayonet type, interposed between the skirt and the wall. The fixing has two male parts (15) forming hooks and two female parts (17) in the form of openings shaped to engage the hooks. A projecting tongue (18) engages in a complementary opening (19) to lock the assembly in place. The tongue is on the external face of the wall of the fan box.
