Abstract: The present invention relates to an antitheft device for locking the steering wheel of any kind of vehicle, comprising a first outer locking element (1; 21), provided with a mechanism (2; 23, 25) for the coupling with a section (3, 3'; 24) of the steering wheel. A second inner locking element (5; 22) is movable with respect to said first locking element (1; 21) and provided with at least a projecting tongue (6; 27) coupling with the steering wheel (3, 3'; 24) and interacting with the coupling mechanism (2; 23, 24). A section of the steering wheel is provided on said first element (1; 21) so as to lock the outer ring of the steering wheel and at least one spoke (4; 29) of the steering wheel. There is an opening and closure mechanism (7, 8, 9, 10, 11; 28) for the antitheft device. A first outer element (1; 21) is provided with a projection interfering with other parts of the vehicle so as to prevent the free rotation of the steering wheel when the antitheft device is on.

Abstract: An antitheft pedal-locking device has a first supporting member extending upwardly, a safety lock coupled to the first supporting member and a shaped member projecting laterally adjacent a lower end of the first supporting member. A second supporting member is slidably coupled to the first supporting member for movement of the first supporting member between a lower locking position and an upper unlocking position. The second supporting member has a projecting member cooperating with the shaped member in the locking position of the first support member for locking a vehicle pedal between them. A base member for resting on a vehicle floor is adjustably connected by a first coupling to a lower end of the second supporting member. A third supporting member is adjustably mounted on the base member by a second coupling. The third supporting member is laterally spaced from and is parallel to the second supporting member.
