The present invention relates to a hose joint clamp which is applied to the joint portion of hoses abutting each other to fasten the hoses together and maintain air-tightness. The hose joint clamp of the present invention prevents the sheath of the hose contacting a band of the clamp from being pushed in accordance with the rotating direction of the band and improves the fastening force of the band. The hose joint clamp of the present invention includes a band which has an outer surface with a thread and is formed into an open ring for wrapping a hose; a fastening screw engaged with the thread to adjust the diameter of the open ring; and a support member which is disposed to contact an inner surface of the band, and has a diameter changing in accordance with the variation of the diameter of the open ring. |
