Abstract
The plunger tube of the handle-bar stem adapted to be blocked in the fork tube of the vehicle is provided at its end with at least one inclined outer face. A nut adapted to cooperate with the inclined face has the same number of inclined faces which are inclined in the opposite direction. An expanding member is tightened against each face of the tube and against the corresponding face of the nut and urged outwardly by the translation of the nut axially of the plunger tube so that the nut bears against the fork tube and blocks the two tubes.
