nozzle

A device, often a pipe or tube attached to the end of a hose, designed to control the characteristics of flow (speed, direction, pressure) of the stream of water that emerges from them. In high-velocity cleaners, various nozzles force the water to exit the nozzle orifices in specific patterns appropriate to the work needing to be done.
