Abstract
Axial displacement of the pins (3) connecting the webs (1) of a rotor rim with the roots of blades (7) is prevented by at least one locking system formed from balls (4) in complementary annular grooves (5) in the pin (3) and the web (1). The balls may be inserted into each groove through an aperture which is then plugged. The pin may be prestressed. <IMAGE>
