Abstract: A flow-regulating device is provided for external placement along a garden hose to control the water flow therethrough. The flow-regulating device comprises an open-ended hollow housing for receiving the hose. A compression member for compressing the hose against the housing. An actuator mounted on the housing for moving the compression member toward and away from the hose thereby controlling the compression of the hose to vary the flow of fluid through the hose. The hollow housing may also have a longitudinal slot therein for inserting the hose.
