1. A closure for a spout of a flexible thin-walled packaging, comprising
a base body irremovably screwable to the spout, comprising an irreversibly yielding guarantee wall;
a cap assembly comprising a cap and a guarantee tab which, in a closed configuration, axially surmounts the guarantee wall;
at least one breakable bridge which, in an intact closed configuration, is integral and joins the guarantee tab to the guarantee wall; and
a flexible hinge that joins the base body to the cap assembly to rotate the cap assembly from the closed configuration to an open configuration in which the cap is disengaged from a spout mouth.
