In addition, when purified water is discharged from the connector 100 to the water outlet hose 300, it is possible to prevent a phenomenon in which water leakage occurs due to the water pressure.

In addition, when purified water is discharged from the connector 100 to the water outlet hose 300, the phenomenon that the water outlet hose 300 is separated from the connector 100 by the water pressure may be prevented.

In addition, since the fixing cap 200 is formed of a transparent material, it is possible to determine whether the supply hose 300 and the connector 100 are coupled from the outside, and whether there is leakage, and the fixing cap 200 is connected to the connector ( 100) or when fitting into the supply hose 300, while visually checking the position of the fastening portion, the fixing cap 200 can be fitted, so that workability can be improved.

In addition, based on the circumferential direction of the connector 100 and the fixing cap 200, since the locking protrusion 210 is inserted into the receiving groove 105 in the entire section rather than a partial section, the connector 100 in the entire section The bonding force between the and the fixing cap 200 may be secured.

In addition, based on the circumferential direction of the fixing cap 100, since the water outlet hose 300 is pressed inward in the entire section rather than some sections, the coupling force between the connector 100 and the water outlet hose 300 in the entire section Can be secured.
