この実施例の管継手の加熱・保温カバーを採用した場合、以下のような効果を奏する。 (About the excellent effect of the equipment with this heating and heat insulation pipe)
When the heating / insulating cover for the pipe joint of this embodiment is employed, the following effects can be obtained.

上述した如く、ケイ素やグラスファイバーなどの保温材では、例えばクイックコネクタを含むような管継手を有するような場合、外部操作ができるようにすることは極めて困難である。   As described above, with a heat insulating material such as silicon or glass fiber, for example, when having a pipe joint including a quick connector, it is extremely difficult to perform external operation.

これに対して、この実施例のものでは、ケイ素やグラスファイバーに変えて合成樹脂で構成された第１・第２カバー部１，２としている。そして、半割り構造体２ａ、２ｂに、図５〜図８に示すように、上記した一対の操作部材７４と対応する部分に押し込み片５（半割り構造体２ａ、２ｂの後部側近傍をコ字状に切り込みを入れて形成）を設けており、第２カバー部２を取り外すことなく、押し込み片５の操作により管継手９に対して雄部材７２を着脱できるようにしてある。第２カバー部２は、管継手９との間に空域が設けられているので、コードヒータＣＨからの熱により保温効果は十分である。   On the other hand, in this embodiment, the first and second cover portions 1 and 2 are made of synthetic resin instead of silicon or glass fiber. Then, as shown in FIGS. 5 to 8, the pushing pieces 5 (the vicinity of the rear side of the half structures 2 a and 2 b are connected to the half structures 2 a and 2 b in the portions corresponding to the pair of operation members 74 described above.
