Squeeze clamps are used to hold hoses in place on a number of low-pressure systems. The most common squeeze clamps can be found on the air intake hose on your car engine. These clamps are made of spring steel which allows them to keep hoses tightly fastened over hose flanges and fittings. Due to the strength of the spring steel, most cannot be removed by hand. Before a hose can be removed, you have to loosen and remove the clamp.
