To provide a water leakage repair metal fixture improved in cutoff performance.SOLUTION: A water leakage repair metal fixture 1 has a plurality of metal bands 3 arranged in a pipe circumferential direction CD of a fluid pipe 2 with intervals, cutoff sheets 5 arranged at internal peripheral faces 3a of the plurality of metal bands 3, formed of elastic bodies, and sealing a clearance between the metal bands 3 and an external peripheral face 2b of the fluid pipe 2, and a fastening mechanism 4 for fastening end parts of the plurality of metal bands 3 in the pipe circumferential direction. An internal peripheral face 5a of the cutoff sheet 5 has a plurality of first ribs 51 extending in the pipe circumferential direction CD, a plurality of second ribs 52 extending in a pipe axis direction AD, and a plurality of first recessed parts 54. The plurality of first recessed parts 54 are formed while being blocked by the plurality of first ribs 51 and the plurality of second ribs 52. An outer end 53e of the outermost rib 53 located at the outermost outside AD1 in the pipe axis direction out of the plurality of first ribs 51 is located at the inside AD2 in the pipe axis direction rather than outer ends 3e of the metal bands 3 in the pipe axis direction.SELECTED DRAWING: Figure 7
