CONNECTOR AND CONNECTING METHOD OF PIPE

According to the present invention, a connector to connect a pipe relates to a connector to install a pipe wherein a fluid flows. The connector comprises: a connecting member wherein the pipe is inserted by a predetermined depth; a counterpart coupled to the connecting member while being transferred in a direction close to the connecting member, enabling the pipe and an internal flow path to be interconnected by the combination; and a parallel assembly fixated and mounted on the pipe from the inner side of the connecting member, and air-tightening a gap between the pipe and the connecting member. The parallel assembly includes: a locking ring to fixate the location of the parallel assembly by pressurizing the outer surface of the pipe when the pipe is inserted; and a parallel assembly integrally coupled to the locking ring, air-tightening the gap between the pipe and the connecting member while being deformed toward the center of the pipe when the connecting member and the counterpart are completely combined. According to the present invention, the connector to connect a pipe shortens the time required for fitting work, provides convenience of the fitting work, and facilitates to confirm a fitting state. Moreover, the present invention is capable of saving costs and improving a prevention of a leakage.
