A fastening device for combining a pressure gauge on an air pump has a connector, a three-way pipe, a screw and multiple fixers. The connector has a first fool-proof plane and a locating hole. The three-way pipe is mounted on the connector and has a second fool-proof plane facing the first fool-proof plane, a threaded hole being aligned with the locating hole, and multiple retaining holes. The screw is screwed through the threaded hole and a distal end of the screw is inserted into the locating hole to fix the three-way pipe on the connector. The fixers are respectively mounted through the retaining holes and are adapted to fix the pressure gauge on the three-way pipe. Accordingly, the fastening device prevents the pressure gauge from being deflective in its combination position and is easy to assemble and has a low labor cost.
