A blade (1) having a fitting (2) for fastening to a hub and an aerodynamic element (10) having a main spar (20) surrounding a bushing (31) for transmitting centrifugal forces and connected to said fitting (2). The blade includes a transmission member (40) for transmitting torsional forces and co-operating with a torsion box. The fitting (2) includes an annular recess (200) defining a first recess (201) and a second recess (202) that are separated by a top separator (211) and a bottom separator (212) locally obstructing the annular recess (200), the blade (1) including a first ring (71) and a second ring (72) reversibly arranged respectively in the first recess (201) and in the second recess (202), each ring (71, 72) being fastened to the top separator (211) and to the bottom separator (212), a ring (71) including a fastener pin (73) passing through said bushing (31) and said fitting (2) in co-operation with the other ring (72).
