1. A dog clutch control device adapted to ensure at least one meshing between a sliding sleeve (5, 8) having at least one series of toothings (9, 10, 14) an axially fixed element (1, 2, 13), comprising and operating system (22, 24, 26, 23, 25, 27) for a cable (20, 21) which slides in a sheath (28, 29) retained by its ends between a first stop (30) connected to a casing (1) and a second stop (31, 32) connected to a support (33, 34) of the operating system ; a fork (16, 17) attached to a shaft (18, 19) which is connected to the cable (20, 21) and which slides in the casing (1), said fork being adapted to displace the sliding sleeve (5, 8) axially ; and a setting spring (39, 40) to urge the axial displacement of the sleeve (5, 8) to mesh it with the fixed member (1, 2, 13), characterized in that the setting spring (39, 40) is disposed between the second stop (31, 32) and the corresponding end of the sheath (28, 29) and a return spring (35, 36) is so interposed between a portion of the casing (1) and a projecting portion connected to the shaft (18, 19) as to ensure that the cable (20, 21) is permanently tensioned.
