The present invention relates to a pipe connection joint. According to the present invention, the pipe connection joint includes: a connection tube (100) having connection units (110, 120) which guide each end of a pipe (P) to be fitted thereto, on both ends thereof; a fixing tube (200) which surrounds and fixes the outer diameter of the pipe (P) by reducing the inner diameter by being fastened by a coupling tool; a pressing member (300) which has an inner peripheral surface surrounding the pipe (P) and is closely inserted into the entrances of the connection units (110, 120); a pressing ring (400) which has a side coming in close contact with the surface of the pressing member (200) and is adhered to the fixing tube (200); and a fastening tool (500) fastening and fixing the connection tube (100) and the fixing tube (200) in a fastening manner. Tilted surfaces (116) and steps (118) are sequentially formed in the connection units (110, 120) of the connection tube (100). An elastic ring (700) is closely coupled to the steps (118) to have the ends of the pipe (P) elastically adhered thereto and sealed. The pressing member (300) is coupled to a pad (340) which is made of a metal material, has multiple O-rings (320) fitted and coupled to a side tilted surface formed to come in contact with the tilted surfaces (116) of the connection units (110, 120), and generate an elastic force when the pressing ring (400) is pressed to a vertical surface on the other side. The present invention enables a worker to easily and reliably fix the joint to connect pipes. |
