To provide a fixture for use in fixing a longitudinal intermediate portion of a soft pipe to a longitudinal intermediate portion of a reinforcement, for hot-water curing or the like of foundation concrete, wherein the fixture enables the soft pipe to be rigidly fixed to the reinforcement without causing harmful collapse of the same, with high efficiency.

The fixture consists of a soft pipe holding portion 4 and a rod fixing portion 5. The soft pipe holding portion 4 is formed of a receiving port 4a, and a recessed portion 4b formed in a deep recess of the receiving port 4a and having a size corresponding to that of an outer periphery of the soft pipe. The longitudinal intermediate portion of the soft pipe 2 is arranged through the receiving portion 4a into the recessed portion 4b, whereby the soft pipe holding portion 4 holds the soft pipe 2. The rod fixing portion 5 allows the longitudinal intermediate portion of the reinforcement 1 to be fixed thereto.
