PURPOSE: A clamp of a hose connector for a vacuum cleaner is provided to quickly and easily couple the hose connector to a flexible hose by forming a screw unit having the same pitch and thread as the flexible hose. CONSTITUTION: A clamp(10) is attached to the outer surface of a connection part of a hose connector(20) and a flexible hose(H), and protects an electric wire of a connecting piece(22) connected to a circular electrode(21) of a terminal(30). The terminal is coupled to the outer circumference of the hose connector. A screw unit(1) is formed at the inner circumference of the clamp, and has the same pitch and thread as the flexible hose. A plurality of protrusion units are formed on the outer circumference of the clamp at regular intervals, and are parallel to the central axis. The protrusion firmly couples the clamp to the flexible hose. A flange(3) is formed at the outer circumference of the clamp, and precisely adheres closely to a ring-shaped protrusion formed at the outer circumference of the hose connector to firmly couple the clamp to the hose connector.
