FIELD: transport engineering.
SUBSTANCE: according to invention, groove in upper cover 16 of coupling 2 for locking pin 1 is made in from of through hole 18 coaxial with longitudinal axis of coupling 2. Locking hole 17 in coupling 2 is of rectangular section. Cross bars 7 and are installed for reciprocation square to steering shaft 14, and are made cylindrical with cross grooves 12. Second cross bar 8 gets into cylindrical space of first cross bar 7 in which one spring 9 of pull-back spring element is fitted. Invention provides convenience in operation, improves reliability of antitheft device against breaking and ensures multipurposeness of device owing to possibility of mounting of coupling 2 without changing its design on steering shafts 14 of different diameter.
EFFECT: improved operation reliability and antitheft protection.
