Closing device for armored cardboard boxes, especially for boxes that when assembled form a rectangular tube with two extreme nozzles, characterized in that each of these mouths has a closing flap that acts comotapa, which has its line of integrity in a flat lower than the edge of the three remaining sides, it being foreseen to practice on the two edges opposed to the initiation of the cover small transversal cuts that delimit a portion of said edge, whose portion is susceptible to push inwards and jump to a position with the opposite angle, constituting stops that prevent the backing of the lid.
