Abstract
The locking device comprises, for each blade, at least one first subassembly with a fork for locking a finger, one of the fork and finger pivoting on a chassis attached laterally to the hub between the linking members of two neighboring blades, the other element being fixed to the linking member and projecting laterally towards the other linking member so that the pivoting element can be moved between a position in which it is engaged over the finger for locking the blade at least in terms of pitch, and a disengaged position for unlocking.
