The auxiliary mechanical steering lock antitheft device for motor vehicles includes a fixed support (4) that houses a lock (5) with sphere (6) activation-deactivation key (12) and an inclined dragging pin (2), a fork slider (1) with shaped section (1') that inserts itself on the shaped axle with the same prismatic instead of circular section (1") of the steering column (10) to prevent the rotation of the column of said steering. Unlike the steering lock devices of the known technique the new steering lock device differs from all the others existing on the market, because the blocking of the steering column is carried out by a fork slider (1) that inserts itself directly on the square axle (1") of the steering column (10), inhibiting its rotation. This solution, unlike the type bush-pin of the known technique allows the normal collapse of the steering column in case of accident, while in the type bush-pin the collapse is prevented by the bush fixed on the steering column, causing further risks to the driver of the vehicle in case of accident. It can be combined with other electrical-electronic antitheft devices,
