Anti-break-through safety barrier able to be used in correspondence with a site to be protected. The anti-break-through safety barrier comprises a plurality of modular elements coupled together so as to slide vertically with respect to the other. Each modular element comprises a stiff and armor-plated protecting wall, which is fixed laterally to a pair of supports. Each modular element is further movable between an inactive position, located below a determined trampling reference plane and a lifted position above the trampling reference plane to define a single compact protecting structure, stiff and armor-plated, anchored to the floor or to the ground.
