The distributor (32), attached to the barrel (30) of a syringe, comprises a body containing a fluid circulation chamber (62), a fluid feed tube (56), an injection tube (60), a pressure tube (64), a measuring tube (66) and a rinsing tube (68). The distributor (32), attached to the barrel (30) of a syringe, comprises a body containing a fluid circulation chamber (62), a fluid feed tube (56), an injection tube (60), a pressure tube (64), a measuring tube (66) and a rinsing tube (68). The rinsing tube is bounded at least partly by the body of the distributor; its outlet end is in the chamber (62), and it has a manually operated valve (70) to open and close it. The valve combines a plug for the rinsing tube and a lever to operate it, with a spring to hold it in the close position.
