In the tube holder 7 shown in FIGS. 6 and 7, since the holder 1 is an elastic material such as rubber, it is difficult to hold each tube 3 reliably. At the same time, since the plurality of pipes 3 are sandwiched by the common lid 5, if any one of the pipes 3 is displaced, the clip 8 is unlocked and the lid 5 is opened, and all the pipes 3 are opened. 3 could not be held. Further, after inserting the tube 3 into the holding groove 2 of the holding body 1, it is necessary to close the lid member 5 and lock the clip 8, so that the workability is poor.

Further, since the tube holders 15 shown in FIG. 8 hold the respective tubes 3 individually in the holding grooves 12, even if one tube 3 is displaced, the other tubes 3 are held. Does not affect the retention of the tube 3. However, when the tubular body 3 is inserted into the holding groove 12, the resistance of the wall 13 is large, and the work of pushing and opening the wall 13 is required, resulting in poor workability. In some cases, the vertical wall portion of the holding groove 12 may fall down to the adjacent position, and it may be difficult to insert the tube 3 into the adjacent holding groove 12.
