Abstract: A locking device (22) for an automobile (10) mounted externally on the automobile frame (12) has an elongate tubular support (24) in axial alignment with a front wheel (15) of the automobile. A locking bar (50) is mounted in telescoping relation witin the tubular support (24) for relative sliding movement between a retracted inoperable position as shown in FIGS. 3 and 4 and an extended operable position as shown in FIGS. 1 and 2. The wheel (15) is turned prior to the extension of the locking member (50), and upon extension the locking member (50), extends alongside the wheel (15) to block return of the wheel (15) to a straight position and block movement of the automobile (10) in a straight path. A lock (42) locks the locking bar (50) in extended position and maintains the locking bar (50) in such locked position upon manually unlocked by a key.
