<p>PROBLEM TO BE SOLVED: To fix the end of an inner tube 2 easily at the adjustment terminal of a perforated pipe. SOLUTION: A fixing member of adjustment terminal of perforated pipe 10 of the present invention comprises a plurality of inner tube receiving parts 14 that receive a plurality of inner tubes 2. Each of the inner tube receiving parts 14 includes, for example, a sheath tube 24 attached to a hole 18 of a body 12. The inner tube receiving parts 14 can have different lengths, enabling the connecting operation with inner tubes 2 to be carried out one by one from a longer inner tube receiving part 14. That is, a plurality of connecting operations can be performed independently of each other and there is no need to perform all connecting operations at once. If an overhang portion 38 is formed at the leading end of the inner tube receiving part 14, the overhang portion 38 can be positioned easily by making it contacted with or placed on the end portion of the inner tube 2. Accordingly, the connecting operation is performed in two phases of positioning and insertion.</p> |
