A releasable clamp system for clamping a wheel component to a vehicle includes a frame member and a cover plate that is pivotally coupled to the frame member. The cover plate is movable between a closed portion where the cover plate and the frame member encompass the wheel component and an open position that permits removal of the wheel component. A lever is pivotally attached to the cover plate and a hook member is pivotally attached to the lever. An adjustment system is used to adjust the clamping force applied to the wheel component by the frame member and the cover plate.
