Balloon balloon device for toys and propaganda essentially characterized by being constituted by a pneumatic elementary pump determined by a cylindrical tubular body closed by one of its mouths except in a central hole for application and fixation of the flanged mouth of the balloon and opened by the opposite for introducing or plugging in a piston also formed by a tube whose outer end is equally closed except in a central hole on whose inner face a single-pass valve appears, there being another analogous valve arranged inside the outer cylinder or body and parallel to the base of this carrier of the opening to which the balloon to be inflated is attached.
