A fluid delivery set has three lengths of flexible tubing. The first length of flexible tubing at one end is connectable to or integral with a supply container for enteral or parenteral fluid, and at the other end is connected to the inlet of a drip chamber. The second length of flexible tubing is connected at one end to the outlet of the drip chamber, and at the other end to the inlet of a retention/connector device that has about a 90.degree. bend therein. The third length of flexible tubing is connected at one end to outlet of the retention/connector device, and at the other end is connectable to or integral with a means for introducing an enteral or parenteral fluid into the body of a patient. Preferably, a tension responsive pinch valve is operatively associated with the second length of flexible tubing.
