A cam lock mechanism used for locking an adjustable steering column in a position comprises a fixed cam (52)defining a geometric reference plane (101) for the lock mechanism, a tensioning member (16), the tensioning member being able to move at least translationally with respect to the fixed cam parallel to a locking axis (100) perpendicular to the reference plane, in a tensioning direction; and a mobile cam (54) able to move with respect to the fixed cam along a pathway in a locking direction and interacting with the fixed cam in such a way that movement of the mobile cam along the pathway in the locking direction causes translational movement of the tensioning member (16) parallel to the locking axis in the tensioning direction. The mobile cam (54) and the fixed cam (52) are configured in such a way that there is a continuous function linking the movement of the mobile cam in the, locking direction with the translational movement of the tensioning member parallel to the locking axis in the tensioning direction, this continuous function having a derivative which is a decreasing son-constant function.
