PURPOSE:To make the insertion and assembling of insertion parts to a pipe easy by providing a press ring and a stop ring body at the inside of a pipe end core positioned at the end of a pipe body, fixing the stop ring body, housing a press packing in the press ring, and pressing by the tip of the press ring. CONSTITUTION:The flange 13 of a pipe end core 2 is positioned at the end of an opposite pipe body 1. In the inner surface of the pipe end core 2, a press ring 3 is provided and a stop ring body 4 is inserted therein, and the stop ring body 4 is fixed to the pipe end core 2 with a knock pin 5. A long groove 10 to advance by leading by the knock pin 5 is formed on the press ring 3. The long groove 10 is fitted slidably to the knock pin 5, a press packing 15 is housed on the tip of the stop ring body 4, and it is pushed by the tip of the press ring 3. As a result, the packing 15 can be pressure-contacted and sealed closely, and a water permeation can be stopped simply. |
