Claim:
An intrusion-prevention enclosure comprising: a plurality of modular panels with respective lateral uprights, and which are mutually associatablo to provide a barrier structure; a plurality of ground support posts; detachable upper retention means provided at said support posts for retention of said lateral uprights of said panels; a plurality of lower collars, which are arrangeable at adjustable heights along said posts; a plurality of wings peripherally distributed on said lower collars, and which are detachably engageable with open lower ends of said uprights; each one of said wings forming a respective lateral supporting surface for receiving a respective one of said open lower ends, each respective open lower end resting on said lateral supporting surface of one of said wings and being allowed to rotate by pivoting around said lateral supporting surface so as to obtain a tilting of said panels in a preset direction, when said retention means is detached so as to be placed in a configuration for releasing said panels, and wherein each one of said wings has a substantially L-shaped cross-section, with a first side attached to said collar and a second side free for insertion in an open lower end of said uprights, said supporting surface being formed by a lower portion of a side wall of the second free side of the L-shaped wing, said lower portion being folded inward toward said collar so as to constitute a lateral step, whereby to allow said panel having its center of gravity outside said supporting surface and being in a position of unstable equilibrium, and not retained in an upper region thereof by said retention means to tilt by rotating in a preselected direction.
