To overcome the disadvantages of connecting the screw nipple to the bushing in a connector for a shower head by a punching operation, there is provided a lock ring which is fitted around a screw nipple of the connector and which has a plurality of protrusions at the periphery thereof. The lock ring is adapted firmly to fin a bushing on an outer hose, the bushing and screw nipple being fitted around an inner hose into which a band nipple of the connector is inserted.
