ABSTRACT:
A drip irrigation device comprising a connector for two lengths of hose which includes a flow restrictor for emitting a drip for use in irrigation. The device includes a core member having a central through passageway and an outer helical rib or thread providing an outer continuous restricted channel between the central passage and the exterior of the housing. An outer member surrounds the channel and can be moved independently of the core member to position clear of the rib to permit flushing the helical channel for the drip irrigation device without twisting or separating the two hose sections.
