Abstract: This fixing device includes a cylindrical core (1) provided with an axial orifice (4) through which the front end (10) of a lever arm (2) can slide with a snug fit. The core includes to the interior a positioning projection (11) and two axial extensions (13) provided with securing projections (14) and linked to a coaxial circular ring (17). The front end (10) of the lever arm (2) includes an axial groove (19) adapted to take the positioning projection (11), and on its centered portion (21) a coaxial securing groove (22) adapted to take said securing projections (14).

Abstract: Locking device for the automatic transmission gearshift lever of automobile vehicles.This device includes a reset mechanism (MR) and a securing mechanism (MF) linked by a control cable (C). The reset mechanism (MR) includes a contact stem (10) linked to the two-position ignition key, parking position and drive position, which correspond with the coupling of the key with the starter switch, and a retaining stem (11) linked to the cable (C). The securing mechanism (MF) includes a traction body (22) linked to the lever (2), to its support (1) and to the cable (C). When the contact (10) and retaining (11) stems are coupled, the traction body (22) locks the trigger (3) of the lever (2), preventing its actuation. Uncoupling of the ignition key requires the lever (2) to be in the parking position, the coupling of both stems (10, 11) taking place automatically.
