A fastening device includes a first annular flange connected to an air intake, a second annular flange connected to a powerplant pressed against the second annular flange and fastening elements that allow the annular flanges to be linked. For at least a first fastening element, a blade is fitted between the first fastening element and the first annular flange, the blade including at least a central part linked to the first fastening element, radially mobile relative to the first annular flange, and at least one offset part for which at least radial centripetal displacement is limited relative to the first annular flange, the central part and the offset part being offset relative to one another along the direction of the circumference.

1. A fastening device between a first conduit of an aircraft nacelle air intake and a second conduit of a powerplant installed in said nacelle, the two conduits being installed end-to-end, said fastening device including: a first annular flange, linked to the air intake,a second annular flange linked to the powerplant pressed up against said air intake annular flange, wherein holes are arranged in the first and second annular flanges, respective holes in the first and second annular flanges being aligned with one another,fastening elements whose shanks are inserted into the holes, allowing link up of said first and second annular flanges, at least a first fastening element of said fastening elements having a shank with a diameter and the hole of one of the first and second annular flanges into which the first fastening element is inserted has a diameter greater than that of the shank allowing play of said shank, andat least one blade interposed between said first fastening element and said second annular flange, the blade comprised of at least two parts comprising at least one central part linked to the first fastening element, radially mobile relative to said second annular flange and at least one offset whose centripetal radial displacements at least are limited relative to said second annular flange, the two parts being offset in the direction of a circumference of the connecting device, wherein:the blade exerts a force on the first fastening element that is proportional to radial movement, towards the exterior, of the first fastening element,the central part comprises a passage hole through which the shank of the first fastening element passes and whose diameter corresponds to that of the shank of the first fastening element,the second annular flange supports at least one stop to limit movement of the offset part along a centripetal radial direction,said stop comprises a shank of a second fastening element of said fastening elements integral to the second annular flange, andthe offset part of the blade includes a passage hole whose dimension in the radial direction is adjusted in diameter to that of the shank of the second fastening element. 2. The fastening device according to claim 1, wherein the passage hole is oblong, has a largest dimension oriented along the circumferential direction so as to allow movement in the circumferential direction of the offset part relative to the second fastening element. 3. The fastening device according to claim 1, further comprising at least one raised element integral with the second annular flange and wherein said stop cooperates with the at least one raised element integral with the second annular flange, the raised element for bearing against an edge of the offset oriented towards the exterior. 4. The fastening device according to claim 3, wherein said at least one raised element comprises two raised elements disposed on either side of the offset part orientated toward the exterior and the stop cooperates with said two raised elements. 5. The fastening device according to claim 1, wherein the blade includes a central part for one of the fastening elements and the at least one offset part comprises two offset parts disposed on either side of said one of the fastening elements, the two offset parts being offset relative to the one of the fastening elements along the direction of the circumference. 6. The fastening device according to claim 5, wherein the at least one blade comprises two adjacent blades include a stop in common, to limit movement of the offset parts of the adjacent blades in a centripetal radial direction. 7. The fastening device according to claim 1, wherein the at least one blade includes several passage holes each planned for a first fastening element. 8. The fastening device according to claim 1, wherein an axis of the passage hole of the annular flange connected to the air intake is offset towards the exterior relative to an axis of the passage hole of the annular flange connected to the powerplant.
