During the folding and unfolding operations the handlebar being slid on the front legs, the device being actuated by means of a rope and having a lock at each side. The lock has a housing having an open lower portion and housing the active element, a flat being slidably fifed to each of the lateral faces of the housing, the flats being connected together at an end at which they are actuated by the rope. Each of the flats in its central region having an oblique slot, a pin extending through the active element being in a position to be shifted along the oblique slots, the active element being transversally shifted in the empty space of the housing when the flats are made to carry out a longitudinally shifting motion and thus bringing about the locking and unlocking with respect to the locking points being provided on the front legs.
