A tarpaulin tensioning arrangement includes a lever or leg mounted at one end to a framework extension. A crank having a threaded end is threadably engaged to the lever. The framework is moved to a tightened condition by rotating the crank until the lever or leg is engaged with a catch to hold one end of the lever or leg in a fixed position. Continued rotation of the crank causes the framework extension to move in a tensioning direction.
