PURPOSE: A rotating filter housing coupling device is provided, which can prevent the damage due to the rubbing of the sealing mounted on the water exit of the filter housing when the filter housing is separated from connector, and the filter housing is simply installed after being rotated by simplifying the coupling structure of the complex mode. CONSTITUTION: A rotating filter housing coupling device comprises; an arc-shaped piece having the contact surfaced on the rear part and the curved surface on the bottom part; a connection part(23) interlinking the arc-shaped piece(22) to be faced with the arc-shaped piece; a collet(20) having a body in a ring shape(21), and forming the connection part with the arc-shaped piece; and a rotating member(30) in a cylindrical shape which forms a pressurization protrusion(31) that pressurizes or contacts the contact surface in the rear surface of the arc-shaped piece. The rotating member forms the pressurization protrusion to contact and pressurize the contact surface of the arc-shaped piece, a locking protrusion(32), and a bonding groove(33).
