PROBLEM TO BE SOLVED: To enable a tube opening/closing clamp to be freely moved on a tube and prevented from its careless movement thereon by providing the first hooking part for fixing the clamp on the tube and the second hooking part for closing the tube. SOLUTION: The way of holding a tube 7 by a clamp is carried out in such a way that an erection part is warped around a bent part 5 serving as a fulcrum by pressing the clamp on its both sides by fingers, a projecting part 91 slips in the firs groove part 93 from the other end part tip end and when fingers are released from the projection piece 2, the projecting part 91 hits the start part of the groove part 93 and is hooked there so that a tube pressing member 6 can hold the tube 7. In order to block the tube, if the clamp is further pressed and a hooking end 92 is hooked below the eaves of an eaves-like part 96, small projecting parts 3 themselves bite each other so as to block the tube 7. Therefore, when the hooking is released, the clamp can be moved freely on the tube but if the first hooking part is hooked, careless movement of the clamp on the tube may not take place. |
