A pipe clamping device that clamps a first pipe and a second pipe each other, the pipe clamping device having an annular case with a central opening into which the first pipe and the second pipe are inserted; a tightening member movable between a tightening location where the tightening member tightens outer circumferential surface of the first pipe and the second pipe and a disengagement location where the tightening member does not impose pressure on the outer circumferential surface of the first pipe and the second pipe; and a stopper restricting radial movement of the tightening member such that the diameter of the tightening member at the disengagement location does not extend beyond a predetermined number, the stopper being prepared in the annular case. The pipe clamping device provides easy clamping of pipes since the tightening member at a disengagement location has a predetermined diameter by the stopper of the case.

1. A pipe clamping device for clamping a first pipe and a second pipe, the pipe clamping device comprising: an annular case with a central opening into which the first pipe and the second pipe are inserted;a tightening member movable between a tightening location where the tightening member tightens an outer circumferential surface of the first pipe and the second pipe and a disengagement location where the tightening member does not impose pressure on the outer circumferential surface of the first pipe and the second pipe, the tightening member being an annular member and being disposed in the inner region of the circumferential surface of the case and releasably combined to the case; anda stopper restricting a radial movement of the tightening member such that a diameter of the tightening member at the disengagement location does not extend beyond a predetermined value, the stopper being formed in the annular case,wherein, to prevent the tightening member from disengaging from the case at the tightening location and the disengagement location, the tightening member comprises a disengagement prevention projection protruded in an outwardly radial direction and the annular case comprises a disengagement prevention groove into which the disengagement prevention projection is inserted. 2. The pipe clamping device of claim 1, wherein the case comprises an insertion guide which is formed along an edge of the central opening and forwardly protruded from the case such that its radius increases gradually in the forward direction. 3. The pipe clamping device of claim 1, wherein the tightening member further comprises: an adjustment screw rotatable in both directions, the adjustment screw having a head part at one end and a thread part at the other endwhereby the tightening member, by the adjustment screw, is gradually movable between the tightening location and the disengagement location. 4. The pipe clamping device of claim 3, wherein the case further comprises: an outer circumferential surface; andan adjustment screw exposure space for disposing the head part of the adjustment screw, the adjustment screw exposure space being concavely formed in the outer circumferential surface of the case such that the head part of the adjustment screw does not protrude beyond the circumferential outer surface of the annular case. 5. The pipe clamping device of claim 3, wherein the tightening member further comprises: an adjustment screw fixing member which is fixed at one end of the tightening member and rotatably fixes the adjustment screw; anda plurality of adjustment slots which are formed at the other end of the tightening member and coupled with the thread part of the adjustment screw. 6. The pipe clamping device of claim 5, wherein the case comprises an adjustment screw mounting space into which the adjustment screw fixing member is inserted in order to prevent the adjustment screw fixing member from disengaging from the case. 7. A pipe clamping device for clamping a first pipe and a second pipe, the pipe clamping device comprising: an annular case with a central opening into which the first pipe and the second pipe are inserted;a tightening member movable between a tightening location where the tightening member tightens an outer circumferential surface of the first pipe and the second pipe and a disengagement location where the tightening member does not impose pressure on the outer circumferential surface of the first pipe and the second pipe, the tightening member being an annular member and being disposed in the inner region of the circumferential surface of the case and releasably combined to the case; anda stopper restricting a radial movement of the tightening member such that a diameter of the tightening member at the disengagement location does not extend beyond a predetermined value, the stopper being formed in the annular case,wherein the rear face of the case is open; the tightening member is disposed in the rear face of the case; a cover which is detachable is coupled with the rear face of the case, the cover being a plate type member with a central opening into which the first pipe and the second pipe are inserted; and the rear face of the case is closed by the cover. 8. The pipe clamping device of claim 7, wherein, to prevent the tightening member from disengaging from the case at the tightening location and the disengagement location, the tightening member comprises a disengagement prevention projection protruded in an outwardly radial direction and the annular case comprises a disengagement prevention groove into which the disengagement prevention projection is inserted. 9. The pipe clamping device of claim 7, wherein the case comprises an insertion guide which is formed along an edge of the central opening and forwardly protruded from the case such that its radius increases gradually in the forward direction. 10. The pipe clamping device of claim 7, wherein the tightening member further comprises: an adjustment screw rotatable in both directions, the adjustment screw having a head part at one end and a thread part at the other endwhereby the tightening member, by the adjustment screw, is gradually movable between the tightening location and the disengagement location. 11. The pipe clamping device of claim 10, wherein the case further comprises: an outer circumferential surface; andan adjustment screw exposure space for disposing the head part of the adjustment screw, the adjustment screw exposure space being concavely formed in the outer circumferential surface of the case such that the head part of the adjustment screw does not protrude beyond the circumferential outer surface of the annular case. 12. The pipe clamping device of claim 10, wherein the tightening member further comprises: an adjustment screw fixing member which is fixed at one end of the tightening member and rotatably fixes the adjustment screw; anda plurality of adjustment slots which are formed at the other end of the tightening member and coupled with the thread part of the adjustment screw. 13. The pipe clamping device of claim 12, wherein the case comprises an adjustment screw mounting space into which the adjustment screw fixing member is inserted in order to prevent the adjustment screw fixing member from disengaging from the case.
