The mechanism has a ramp (31) and a spring plate (36) for retaining a neutralization lever (27) in an active state during rotation of a flange with respect to another flange from a front adjustment position towards a back adjustment position. The ramp and the spring plate release the neutralization lever during rotation of the former flange from the front adjustment position towards the back adjustment position in a determined normal position of the former flange with respect to the latter flange, where the normal position is distinct from the front adjustment position.
