<p>PURPOSE:To facilitate a check of an insertion condition of a connecting pipe so as to prevent an insertion defect or a fusion defect previously by arranging an indicator which is projected/moved in the outer circumference direction when the connecting pipe is inserted in a pipe mounting part in a joint main body. CONSTITUTION:An electrically fusing joint part 2 is provided with an internal thread 6 to be screwed to an external thread 5 of a joint main body 1, and on the opposed side end part inside face of the internal thread 6, a pipe mounting part 15 brought into contact with the outside face of a pipe to be connected is arranged. A connector pin 16 is projected to the end part outside face of the electrically fusing joint 2, and on the inner thread 6 side, a hole 13 through which the indicator 3 is projected is formed. The indicator 3 is provided with a pressing contact part 11, which is brought into contact with the end face of the connecting pipe so as to be pressed, and a bent part 12, which is fitted in the hole 13 of the joint part 2 and is bent when the pipe is inserted, and the bent part 12 of the indicator 3 is raised by a pressing pressure when the pipe is completely inserted into the pipe mounting part 15, so that the indicator 3 is projected from the hole 13 and indicates that the insertion is finished.</p> |
