The invention relates to a steering column comprising: an upper body (1), two connection flanges (22, 23) for connecting the upper body (1) to a support element (2), and a device for tightening and blocking the upper body (1) in position on an internal tube (4). The aforementioned tightening and blocking device includes: a clamp screw (5) extending through the flanges (22, 23); a set of cams comprising a fixed cam (8) and a movable cam (9) mounted such that it can move freely in translation along the clamp screw (5) and arranged so that it can bear on one of the flanges (23); a rack (10) capable of co-operating with a notched arrangement provided on the other flange (22); and a resilient means (11) arranged between the movable cam (9) and the rack (10) in order to exert a return force on the rack in the direction of the notched flange (22). |
