Linking device more specifically suited to providing the link between an air intake and an engine of an aircraft nacelle

The nacelle has a connecting device comprising an annular flange (46) that is connected to an air inlet (42), and another annular flange (50) connected to a motor (44) that is pressed against the former flange. The flanges extend in a plane perpendicular to a longitudinal axis of the nacelle. Connecting elements i.e. bolts, are placed in respective bolt holes (48, 54) for connecting the flanges. One of the flanges comprises a U- or V-shaped opening (72) located between the bolt hole and a junction zone (68) of the flange and/or between the bolt hole and an outer edge (74) of the flange.
