か、制作コストも低廉になし得る。The electric wire protection tube A having the function of preventing sticking according to the present embodiment has the above-described configuration, and the projecting pieces 4, 4, 7, and 7 of the tube body 1 and the joint tube B are expanded right and left. The divided parts 3, 6 and 10 are opened, the electric wire W installed therebetween is inserted, and the protruding pieces 4, 4 and 7, 7 are closed, and the respective oblong holes 5,
5 is inserted and tightened with the insulating lock band 12.
Next, a second wire protection tube A is attached to the wire W in the same manner as described above, and the fitting flange 2 at one end is pushed into the joint pipe B of the wire protection tube A to be fitted. The electric wire protection tube A is connected by engaging with the holding portion 8. Hereinafter, the same operation is repeated, and a plurality of electric wire protection tubes A are continuously attached to a required section of the electric wire W installed as shown in FIG. In this manner, the electric wire protection tube A can be connected efficiently and efficiently through the joint tube B. In the present embodiment, if a yellow paint is applied to the outer peripheral surface of the anti-stick material layer 9, the inner layer portion 1b to which the yellow colorant is added becomes unnecessary, and molding can be facilitated by this amount. In addition to that, the production cost can be reduced.

れて落ちるといった危険もない。Therefore, even if, for example, a squirrel, which is a rodent, may bite the electric wire protection tube A during use, the electric wire W is surrounded by the anti-harmful substance layer 9 as shown in FIG. Moreover, since the wire W cannot be deeply bitten by hitting the bite prevention layer 9, it is possible to reliably prevent the wire W from being bitten and damaged. In addition, when the outer layer portion 1a is bitten and the inner layer portion 1b is exposed, yellow, which is different from black of the outer layer portion 1a, appears and it is possible to visually recognize that the damage has occurred, and it is possible to know the situation of the damage. It is possible to take measures such as updating immediately. If there is no bite, the outer layer 1a is made of a material having good weather resistance and is colored black, so that it can be used stably for a long time with little deterioration in weather resistance, and in the surrounding environment. Can also be used by matching. Furthermore, even if the electric wire protection tubes A are turned upside down by the wind, the two projecting pieces 4,
Since 4 is firmly joined to the insulating band 12, the divided portions 3 and 6 do not open, and there is no danger that the electric wire W comes out from there and the electric wire protection tube A comes off unnecessarily and falls.

The same parts as those of the electric wire protection tube A of the present embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In the electric wire protection tube A1 shown in FIG. 6, a fine mesh stainless steel wire mesh is curved into a cylindrical shape to form the anti-stick layer 9 (9b). The use of the wire mesh in this way improves the flexibility and facilitates the expansion of the divided portion 10, as well as the reduction in weight and the ease of handling.

Since it is formed by integral molding of the resin, the molding is extremely easy and the production cost can be reduced. Further, since the weight can be reduced, the workability of mounting on the electric wire can be improved. Any of the embodiments shown in FIGS. 6 to 8 can sufficiently achieve the purpose of preventing rodents from being harmed similarly to the present embodiment.
In addition, it goes without saying that the electric wire includes a distribution line, a communication cable, and the like.
