Next, the tubular portion 6 of the terminal protection tube 5 is connected to the inner tube 1 and the sheath tube 2.
Insert between Then, the inner pipe 1 is made to protrude from the upper end of the pipe joint storage section 7. At this time, the projecting length of the inner pipe 1 is set to such a length that the work of grasping the end of the inner pipe 1 by hand and connecting to the pipe joint 3 can be easily performed. Thereafter, the end of the inner pipe 1 is inserted into the pipe joint 3, and the pipe joint 3 is tightened to fix the inner pipe 1. Next, the terminal protection tube 5 is pulled up and the fitting 3 is placed in the fitting storage section 7.
To store. The length of the tubular portion 6 of the terminal protection tube 5 is set in advance so that the lower end of the tubular portion 6 is located in the sheath 2 in a state where the fitting 3 is stored in the fitting storage portion 7. .

(Japanese Utility Model Laid-Open No. 4-50463). This terminal protection tube attaches the sheath tube mounting part to the end of the sheath tube, works to connect the inner tube to the pipe joint with the bellows tube portion contracted, and then extends the bellows tube portion to extend the tube. By accommodating the pipe joint in the joint accommodating portion, the same effect as described above can be obtained.

とさや管の間に深く挿入することができなくなる。However, in the terminal protection tube shown in FIG. 5, it is necessary to insert the tubular portion considerably deeply between the inner tube and the sheath of the double tube. If the tube is bent near the joint, it is difficult to insert the tubular portion because the inner tube and the sheath tube are in strong contact with each other due to the repulsive force against bending. A silencing tape may be interposed between the inner tube and the sheath to prevent noise from being generated when the inner tube and the sheath collide with a water hammer. Since there is almost no gap between the tube and the sheath, the tube portion of the terminal protection tube cannot be inserted deeply between the inner tube and the sheath.

It is necessary to press down in a contracted state against the elasticity, and there is a problem that work is difficult.

A bellows tube portion capable of self-holding is provided, a sheath tube mounting portion is formed at one end of the bellows tube portion to be mounted on a double-pipe sheath, and a pipe joint for an inner tube is housed at the other end side. A pipe joint accommodating portion is formed, and a stopper portion for engaging with a corrugation of the sheath tube is formed in the sheath tube mounting portion.

Since the diameter of the top of the mountain and the diameter of the bottom of the valley are constant, the longer slope g and the shorter slope h as shown in FIG.
Is on both sides of the top of the mountain (extended state), the shape can be stably maintained, and the shorter slope h enters the longer slope g as shown in FIG. ), The shape can be stably maintained. Therefore, the extended state and the contracted state can be maintained by themselves. The angle θg between the surface passing through the top of the mountain and one slope g is larger than the angle θh between the surface passing through the top of the mountain and the other slope h.

The inner pipe 1 is protruded from the end of the inner pipe 1 by a required length. Next, with the terminal protection tube 11 in a state where the bellows tube portion 12 is contracted, the inner tube 1 is inserted thereinto, and the sheath tube attachment portion 13 is attached to the end of the sheath tube 2. Then, the ridge 15 on the inner surface of the sheath tube mounting portion 13 is formed.
However, since the sheath tube 2 bites into the valley portion of the waveform, the sheath tube mounting portion 13 cannot easily be pulled out of the sheath tube 2.

たがってこの作業もきわめて容易に行える。Next, as shown in the center of FIG. 2, the end of the inner pipe 1 is inserted into the pipe joint 3 and tightened and connected. Since this operation is performed while the bellows tube portion 12 of the terminal protection tube 11 is in a contracted state, there is no need to press down the terminal protection tube 11 and the operation can be easily performed. Next, as shown on the right side of FIG.
4 is pulled up, the bellows tube part 12 is stretched, and the pipe joint 3 is stored in the pipe joint storage part 14. At this time, since the sheath tube mounting portion 13 is locked to the sheath tube 2 by the ridge 15, it does not come off from the sheath tube 2. Further, the bellows tube portion 12 can hold its shape after being stretched by itself. Therefore, this operation can be performed very easily.

It can be easily attached to the end of the pipe. In addition, since the bellows tube part can hold the stretched state and the contracted state by itself, and the sheath tube mounting part has a retaining part that engages with the sheath tube waveform, so when connecting the inner tube to the pipe joint And
When checking the connection state between the inner pipe and the pipe joint, there is no need to hold down the bellows tube in a contracted state, and it is not necessary to hold down the sheath mounting portion when stretching the bellows tube. Therefore, connection work and inspection work can be easily performed.
