Abstract: A general retaining device for use with utility vehicles, such as fork lift trucks, tractors, construction and agricultural machines, and public utility vehicles for protecting the driver from centrifugal forces. The invention is attached to all canopy guards with front and rear struts, and is open on all sides. The side openings of the canopy guard protecting the driver are divided by means of an approximately horizontally extending support which is pivoted on the one strut by a hinge and retained on the other strut by means of a locking system.
