See For example Scienceware Acetyl Screw Clamp, Cat. No. 05-830, from Fisher
Scientific at www.fishersci.com (search for 05-830 for a description).
Unfortunately there is not an illustration on line (there is in my print
catalog), but except that this one is plastic not metal as you probably used
in chemistry class, this is most likely what you recall using (just barely).

There are kinder close-off gadgets - you may remember them (I can just !)
---From your school chemistry days. A metal frame, hardly bigger than the
tube,
with a screw down bar cuts off the flow. Don't like taps at all- more items
for the check list. Why don't taps have contacts so we can wire in warning
lights !
