A mechanical chock has a pair of anchoring cams mounted in rotation and in opposition on a common support spindle. Each cam includes a bearing surface having a predetermined profile. The bearing surface of the first cam presents a convex face, whereas the bearing surface of the second cam has a concave face, so as to obtain three bearing points or zones in the separated blocking position.
