    • PROBLEM TO BE SOLVED: To provide a compact chain cutting and connecting device which can be used at a sprocket wound part of a chain, receives working loads on two positions and is excellent in durability.
      SOLUTION: A pressing member 6 is screwed to a first block 2, and in addition, a coupling member 5 is fixed. A second block is rotatably coupled via the coupling member 5 and has a bottomed hole 3c at one of sides and a through-hole 3b on the other side. A leading protrusion 11b of a tap screw 11 to be screwed with the first block 2 is engaged with the bottomed hole 3c or the through-hole 3b to be positioned. The arrangement thus constituted is attached to the chain from an open part C.
