Abstract: A security lock for vehicles, especially for the cargo compartments of lorries or vans, but also usable on other doors, uses a clamp having two halves or plates such that same hold a bolt, increasing the contact area in the event of a possible attack or leverage, and, if the surface of the vehicle becomes deformed, the two halves jam the bolt, further increasing security and reducing the possibility of opening. In the security lock, the system of inside opening by a cable is eliminated. Further, opening from the inside of the vehicle is performed by rotating a shaft or handle perpendicular to the surface of the vehicle, preventing the vehicle from being accessed from the outside.

Abstract: The present invention relates to a security lock for vehicles, especially for the cargo compartments of lorries or vans, but also usable on other doors. The lock system uses a clamp having two halves or plates such that same hold a bolt, increasing the contact area in the event of a possible attack or leverage, and, if the surface of the vehicle becomes deformed, the two halves jam the bolt, further increasing security and reducing the possibility of opening. Using this invention, the system of inside opening by means of a cable is eliminated. Now, opening from the inside is performed by rotating a shaft or handle perpendicular to the surface of the vehicle, preventing the vehicle from being accessed from the outside.
