A disposable container for forming the end wall of the open end of a barrel of a syringe and for being retained thereon by the resilient interaction of a surface of the barrel and the resilient periphery of a circumferential flange at the intersection of a substantially rigid first wall portion and a flexible second wall portion of the container. Preferably the resilient periphery flexes when pressed into the barrel and then springs out to engage an annular channel-like area in the barrel.
