PURPOSE: A fluid supply hose connecting device is provided to prevent the separation of a hose caused by the discharge pressure of fluid by stably tightening the periphery of the hose by the elastic force of a coil spring. CONSTITUTION: A fluid supply hose connecting device comprises a body(100), a combining housing(200), a coil spring(300), a spring adjusting unit(400). The body comprises a connecting plate(110), a housing combining portion(120), a first spring fixing unit(130), a hose contact portion(140), a hose support portion(150). The connecting plate is fixed to a pipe(10) for supplying and receiving fluid. The first spring fixing unit protrudes form the bottom of the housing combining portion. The hose contact portion is formed on the lower part of the housing combining portion, and connected to a hose(20). The hose support portion is formed with a wider diameter than the hose contact portion, and placed at the lower part of the hose contact portion. The combining housing is connected to the housing combining portion by threads. The coil spring wraps the outer surface of the hose connected to the body. The spring adjusting unit rotates one end of the coil spring, and tightens or loosens the coil spring.
