のテーパ部の奥に位置させるようにしたものである。(Prior Art) A seal packing used for a pipe joint portion needs to be inserted with a sufficient insertion allowance from the mouth of the inner diameter portion where the seal packing is inserted in order to keep a good contact with the inner diameter portion. As a means of inserting in this way, the actual publication is Sho 63-983.
There are two means shown in 1, one of which is to provide a connecting pipe with two locking projections and to fit a seal packing, and to fit a washer having a cylindrical portion to the connecting pipe. The locking projection is pressed from the outside toward the inside of the connected body at the part so that the seal packing is positioned deep inside the inner diameter of the connected body. A seal packing is fitted between the two locking projections near the tip end, and a spacer ring is fitted near the rear end so that the seal packing is positioned deep inside the tapered portion at the mouth of the inner diameter portion.

難になる。(Problems to be Solved by the Invention) In each of the above-mentioned conventional techniques, since the connecting pipe is provided with the two locking protrusions, the process of forming the locking protrusions is troublesome and the dimension of the portion becomes long. In the case of the type that holds the seal packing with the locking projection, the seal packing may get over the projection and come off at the time of connection unless the height of the locking projection is sufficiently large. However, since it is necessary to mount the spacer ring before molding the locking projection, it becomes more difficult to form the locking projection.
したがって本考案は、１個だけの係止突起を有する接続
管を使用して、シールパッキンを被接続体内径部に充分
な挿入代をもって深く位置させることができ、かつ接続
管を正しく保持できる接続装置を得ることを課題とす
る。Therefore, the present invention uses a connecting pipe having only one locking projection to allow the seal packing to be deeply positioned in the inner diameter of the body to be connected with a sufficient insertion allowance and to properly hold the connecting pipe. An object is to obtain a device.
