A device is provided for maintaining the throttle of an internal combustion engine in a fixed position, the device including quick release means for the throttle. A friction device, such as a caliper brake, is provided for frictionally engaging the throttle rod to retain it in a predetermined position. The caliper brake is capable of gripping a section of the throttle rod and an electrical solenoid is capable when energized of urging the brake into engagement with the throttle rod to restrict its movement. A holding circuit incorporating the solenoid means for interrupting the circuit and thus disengaging the caliper brake to release the throttle, includes a hydraulic brake switch, a toggle switch and an ignition switch.
