A flexible clamping device for a pipe of a sprinkler is provided to connect securely a connecting pipe and a clamping unit and to improve the flexibility of a clamping unit by using a spiral type flexible pipe. A flexible coupling device for a pipe of a sprinkler comprises a sprinkler connecting pipe(10), and a compressing seal(30), a compressing bushing(40), and a clamping holder(50). The sprinkler connecting pipe consists of a sprinkler(2) at one side, a screw unit at an outer end of a clamping unit(11) inserted into a spiral type flexible pipe(1) at the other one side, and an inclined surface(12) and a step(13) at the inner part. The compressing seal, the compressing bushing, and a clamping holder are placed between one side clamping unit of the sprinkler connecting pipe and a compressing cap to fasten the spiral flexible pipe.
