The tamper-proof closure of at least one of the end walls of a prismatic cardboard packaging, which can be erected from a flat, cutout and grooved blank, is provided by two foldable flaps 106, 100 hanging respectively from two opposite lateral walls. The flap 106 is fitted with an elongate narrow slot 150, while the flap 100 is extended by a flexible tab 156 comprising two end extensions 158, 160 capable of being folded down along the body of the tab with a view to introducing the tab into the slot. The end extensions are capable of being unfolded by a spring effect after complete introduction of the tab into the slot. <IMAGE>
