Brass Stoddard Test Tube Clamp w Finger Grips – 5 Inch Length

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 brass 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.
