Is there a way to plug excess air pump ports?

We got an air pump with two ports but only need one. Is there a way to plug the extra one? It didn't come with any caps or anything for that purpose. It's this petco air pump:

Just cut about 1-2 inch of the air tube, seal or tie one end, make sure no air can pass through, then just plug the other end to your unused ports.

Geez, that's brilliant. Thanks! That's why I love this place. :)
