a transmission casing including a housing, the housing including a first positioning face and a second positioning face, the first positioning face and the second positioning face forming a positioning slot;
a movable pawl comprising a locking finger, the movable pawl being pivotingly mounted in a plane about a pivot axis on the transmission casing between a locking position in which the locking finger is engaged in the locking recess and a release position in which the locking finger is disengaged from said locking recess, the movable pawl comprising a cam surface;
an actuator that moves a pushing device, the pushing device including a cam follower able to move on the cam surface to move the movable pawl from the release position to the locking position; and
a guide rail including a guide wall guiding the movement of the pushing device and a positioning wall,
wherein the positioning wall of the guide rail is inserted in the positioning slot of the housing, and
wherein the positioning wall and the guide wall form a single wall both extending substantially in a direction parallel to the movement of the pushing device, the positioning wall including at least one protuberance extending substantially in the direction parallel to the movement of the pushing device from the guide wall, the at least one protuberance facing the first positioning face and/or the second positioning face of the housing.
