あるため、好適な係合力が得られる特徴もある。For example, JP-A-8-226587 discloses two half-cylinder members capable of covering a corrugated pipe by a half circumference.
A pipe joint for connecting two corrugated pipes by contacting each other from outside in the radial direction with the vicinity of the end of the corrugated pipe interposed therebetween is disclosed. On both side edges of the semi-cylindrical member, a first engaging means formed in a protruding edge shape protruding laterally, and a second engaging means formed in a hook shape extending outward. The first engagement means and the second engagement means are provided in pairs on both sides of the longitudinal central portion of the half-cylinder member. The two half-cylinder members are formed in the same shape, and the second engaging means in one half-cylinder member causes the other half-cylinder member to be pressed from the outside in the radial direction with the contact surfaces facing each other. The first engagement means of the member is engaged with the second engagement means of the other half-cylinder member, and the first engagement means of the one half-cylinder member is engaged with the two half-cylinder members. Then, it can be suitably mounted on the target corrugated pipe. In such a pipe joint, since a half-cylinder member having the same shape can be used, it is possible to reduce the manufacturing cost of mold equipment for forming the half-cylinder member, and to manufacture the half-cylinder member at low cost. There are benefits to gain. In addition, since the hook-shaped second engaging means is engaged with the protruding edge-shaped first engaging means, a suitable engaging force is obtained.

が殆ど不可能となる問題点も指摘される。The work of installing a pipe joint on the corrugated pipe is performed at a cable installation site where soil, sand, dust and the like are scattered. At the time of connection, foreign substances such as the soil, sand, and dust often intervene between the half-cylinder member and the corrugated pipe,
In such a case, it is necessary to disassemble the combined half-cylinder members to remove the foreign matter, and then perform the re-wrapping operation again. However, in the pipe joint disclosed in the above publication, the second engaging means in each half-cylinder member engages with the corresponding first engaging means in opposite directions along the connecting direction of the two half-cylinder members. Therefore, there is a disadvantage that it is extremely difficult to disassemble the two half-cylinder members after the connection. That is, in order to disassemble the two half-cylinder members, a tool such as a driver is simultaneously inserted between the inclined surface of each of the opposing second engaging means and the base of the first engaging means, so that both the first and second half members are disengaged. Although it is necessary to release the engagement between the engagement means, the attempt to release the engagement between the first and second engagement means is made by the engagement between the other first and second engagement means. It acts to make it difficult to release the engagement, and if it is attempted to release the engagement, it becomes rather difficult to release the engagement. Further, when each half-cylinder member is mounted on the corrugated pipe in an up-down relationship, the second engagement means of the half-cylinder member located on the upper side is oriented downward, so that the second It is pointed out that a tool cannot be used for the engaging means, and that both half-cylinder members are almost impossible to disassemble.

There is also a disadvantage that the two half-cylinder members are combined in the state. That is, each semi-cylindrical member is formed with a convex portion for positioning each other and a concave portion matching the convex portion, and if the convex portion and the concave portion are properly fitted, proper positioning is performed. However, the engagement between the projections and the recesses is made immediately before the two semi-cylindrical members are brought into close proximity and almost completely joined. Therefore, at the time when the half-cylinder members begin to be pressed together, these convex portions and concave portions are not yet aligned, and if they are coupled under appropriate positioning, these convex portions and concave portions will not be aligned. The first engagement means and the second engagement means may be engaged without being fitted. Therefore, in addition to the fact that the disassembly is difficult as described above, various problems are inherent in the conventional pipe joint including the pipe joint disclosed in the above publication.
