A lightweight barrier with locking devices at the top, middle, and bottom. Each barrier has an I-shaped male tab and a matching female slot. The I-shaped male tab is inserted into the female slot on an adjacent barrier. Locking pins are inserted through lower end upper extensions of the I-shaped male tab of the barrier near the bottom and the middle. The locking pins extend through both barriers such that the first and second barriers are secured together at the bottom and the middle. Another locking device is positioned at the top of the barrier which consists of a hinged locking bar held by a hinge pin. When the barrier is mated with an adjoining barrier, the hinged locking bar extends over the adjoining barrier to fit within a locking cavity. The locking bar is then secured to the other barrier to retain it in the locking cavity. The combination of the I-shaped male tab, the locking pin, and locking bar secure the top, the bottom, and the middle portions of the adjacent barriers together, thereby preventing the barriers from twisting and separating which in turn prevents a vehicle from breaking through the barrier.
