本発明は、ニップルなどの配管継手にホースなどの管体を接続し、この管体を配管継手にクリップで固定する配管継手構造に関するものである。   The present invention relates to a pipe joint structure in which a pipe body such as a hose is connected to a pipe joint such as a nipple and the pipe body is fixed to the pipe joint with a clip.

配管継手構造として、ホースジョイント（配管継手）の両端からホース（管体）を差込み、これらのホースをホースジョイントにホースバンド（クリップ）で固定するものが実用に供されている。
図１５（ａ）〜（ｄ）は従来の配管継手構造の基本構成及び接続手順を説明する図である。
（ａ）において、配管継手構造３００は、ホースジョイント（配管継手）３０１、ホース（管体）３０２，３０２及びホースバンド（クリップ）３０３，３０３から構成するものである。図中、３０４，３０４はホースジョイント３０１のジョイント部、３０５はホースジョイント３０１のフランジ部（ベース部）を示す。 As a pipe joint structure, a hose (pipe body) is inserted from both ends of a hose joint (pipe joint) and these hoses are fixed to the hose joint with a hose band (clip).
FIGS. 15A to 15D are views for explaining a basic configuration and connection procedure of a conventional pipe joint structure.
In (a), the pipe joint structure 300 is composed of a hose joint (piping joint) 301, hoses (tubing bodies) 302 and 302, and hose bands (clips) 303 and 303. In the figure, 304 and 304 denote joint portions of the hose joint 301, and 305 denotes a flange portion (base portion) of the hose joint 301.

（ｂ）において、ホース３０２，３０２をホースジョイント３０１に差込んだときに、ホースバンド３０３，３０３がホースジョイント３０１に干渉しない位置までホースバンド３０３，３０３をホース３０２，３０２に予め矢印ａ１，ａ１の如く貫通させる。   In (b), when the hoses 302 and 302 are inserted into the hose joint 301, the hose bands 303 and 303 are previously placed on the hoses 302 and 302 by arrows a1 and a1 until the hose bands 303 and 303 do not interfere with the hose joint 301. It penetrates like this.

（ｃ）において、ホースバンド３０３，３０３を貫通済みのホース３０２，３０２を、ホースジョイント３０１のジョイント部（両端）３０４，３０４に矢印ａ２,ａ２の如く差込む。   In (c), the hoses 302, 302 that have passed through the hose bands 303, 303 are inserted into the joint portions (both ends) 304, 304 of the hose joint 301 as indicated by arrows a2, a2.

（ｄ）において、ホースバンド３０３，３０３をジョイント部３０４，３０４位置まで矢印ａ３，ａ３の如く戻し、ジョイント部３０４，３０４にホースバンド３０３，３０３でホース３０２，３０２を固定する。   In (d), the hose bands 303 and 303 are returned to the positions of the joint portions 304 and 304 as indicated by arrows a3 and a3, and the hoses 302 and 302 are fixed to the joint portions 304 and 304 with the hose bands 303 and 303.

すなわち、実用の配管継手構造は、上記に示したように、ホースジョイント３０１にホース３０２，３０２を差込み、これらのホース３０２，３０２をホースバンド３０３，３０３で固定すれば実用上十分であった。   In other words, the practical piping joint structure is practically sufficient if the hoses 302 and 302 are inserted into the hose joint 301 and the hoses 302 and 302 are fixed by the hose bands 303 and 303 as described above.
