Abstract

A system for locking, with respect to rotation and translation, the engagement of a first shaft with a second shaft, the first shaft being disposed in an axial bore in the second shaft. The system includes a locking device movable between a locking position and a release position, the first shaft having an end part which includes two walls inclined towards each other in a transverse direction, the axial bore having two corresponding walls opposite the inclined walls of the first shaft wherein changing the locking position of the locking device causes a transverse movement of the end part which puts the inclined walls of the first shaft in abutment against the corresponding walls of the axial bore.
