Modular anti-intrusion barrier, comprising a single body which is, at one and the same time, an access-control barrier and a stop-barrier, linked to each other by a release mechanism, which activates the stop-barrier allowing, once loaded, an instantaneous, extremely high-powered action, and by the fact that it is placed on the groundwherein the loading of the modular anti-intrusion barrier is assured by the lowering of the stop-barrier, which tightens the spring, and by the fact that the stop-barrier is maintained flush by a bolt, the movement of the control barrier into a vertical position being obtained by activating a manoeuvering lever operatively connected only with said control barrier.
