Claim:
An anti-break-through safety barrier able to be used in correspondence with a site to be protected, comprising a plurality of modular elements coupled together so as to slide vertically one with respect to the other, wherein each of said modular elements comprises a stiff and armor-plated protecting wall, which is fixed laterally at both its ends to a pair of opposed supports, and wherein each of said modular elements is movable between an inactive position, located below a determined trampling reference plane (P) defined by a road surface, and a lifted position above said trampling reference plane (P) to define a single compact protecting structure, stiff and armor-plated, anchored to the floor or to the ground, wherein said modular elements define a telescopic structure able to slide vertically one inside the other, and wherein each pair of said supports include portions which also telescope and are able to slide vertically one inside another, and wherein in the inactive position all the modular elements and the supports are lowered below said reference plane (P) and are contained inside a compartment made under the road surface.
