What do you call this tool that attaches to an air compressor so your tires can get a boost?

If you've ever gone to a gas station and inflated your tires, you've used this tool. A tire inflator connects to your mechanic's air compressor to quickly add enough gas to reach the desired level. This device also includes a pressure gauge to prevent overfilling.
