This tool easily holds a spring-type hose clamp in the released position when removing a hose secured by that type of clamp or performing similar work. Squeeze the hose clamp tabs with your pliers, then simply insert this tool to keep the clamp released. The tool itself is small, so it does not get in the way of subsequent work such as removing the hose. The ends have 2 different groove sizes to accommodate a wide range of hose clamps.
