PURPOSE: A clamp device for connecting pipes is provided to maintain the airtightness of connected pipes because a bolt and a nut are not easily unfastened by external influences and vibration. CONSTITUTION: A clamp device for connecting pipes comprises a first rotating member(100), a fixing member, a movable member(500), and an operating member(400). The fixing member is perpendicularly installed from the top of the first rotating member to an elongated hole(110). The movable member is fixed to the fixing member with an elastic member and allowed to be rotated. The movable member comprises a fitting hole(510) in one side, a stop protrusion(540) in the bottom side, a protruding portion(520) in the front side, and a stop projection(530) in the rear side. The stop protrusion is fitted into a fitting groove(130) and the movable member is selectively fitted into an anti-loosening groove(810). The operating member comprises rotary knobs(410) and a cam unit(421). The rotary knobs are installed on both sides of a connecting piece(420) penetrating through the elongated hole of the first rotating member. The cam unit is formed on the outer periphery of one side of the connecting piece and operates the protruding portion of the operating member.
