It is a clamp that holds a test tube -- for instance to hold a test tube while heating it without getting burned. It is made from a thick piece of metal wire that is shaped into a spring-loaded clamp to securely hold a test tube.
Note the difference between a test tube clamp, and a test tube rack. A clamp is a way to hold a single test tube while heating the contents inside without actually touching the test tube itself. A rack is instead used to hold many test tubes at once in an upright position. See the Related Questions links below for more information on test tube racks.
You can buy specific test tube holders made of metal, which grip the tube. Alternatively, a large wooden clothes peg with one handle longer than the other. However, this latter design cannot be used when heating the tube with a Bunsen Burner.
