PROBLEM TO BE SOLVED: To provide a fastening instrument strong in a fastening force and simple in structure, which partitions one bag into two parts at an intermediate portion thereof with a strong fastening force and causes no mixture of two liquids existing in spaces on both sides partitioned by it until the time immediately before the actual starting of instillation. SOLUTION: This fastening instrument comprises a base member A and a cam member B. The base member A has engaging walls 2, each being provided on each of both sides of the central main body 1 thereof so as to be engaged with the cam member B. The central main body 1 is composed of a central flat portion 1a and a rear wall 1b orthogonal thereto, and a stopper 5 is provided to each of both sides of the central flat portion 1a. The cam member B has shaft portions 6, each of which is provided on each of both sides of the cross-sectionally circular central body 7 thereof to be rotatably engaged with each of engaging recesses 3 provided in the engaging walls 2 of the base member A. Further, the central body 7 has a handgrip part 8 and a rotation restricting piece 9 provided at a position deviated by 90 degrees from the position of the handgrip part 8. |
