Coupling means for test tubes and the like, the coupling means enabling the coupling of test tubes to other objects or devices for various purposes, as for example, support purposes. In one embodiment of the invention, the coupling means is comprised of a flexible, resilient, tubular body portion which is open at each end and which is adapted to be slidably circumposed on a portion of the periphery of a conventional tubular test tube of the type that is closed at one end, the coupling means also including a pair of circumferentially spaced, flexible, resilient and integral flange portions which project longitudinally outwardly from one end of the tubular body portion and which define openings adjacent the free ends thereof adapted to receive a cooperating member such as the stem of a conventional funnel, a support rod, a thermometer or other object to which it is desired to couple a test tube. In another embodiment of the invention, the coupling means is formed integrally with the body portion of a test tube.
