The present invention relates to a pipe fitting device which connects two pipes The pipe fitting device includes a body which is formed into a hollow pipe shape and which includes fixing protrusions on the center of the outer surface of the pipe, male screw units on edges of both sides of the pipe, flat surfaces between the male screw units and fixing protrusions, and vertical adhesion units on both sides of the protrusion unit; a stop collar which is loosely press-fitted into the flat surface and freely rotated; nut members screw-joined to the male screw units formed on the edges of both sides of the pipe; first and second ferrules which are fitted between the ends of the pipe and the nut members and which move to the center of the pipe by fastening the nut members and press the pipe; an elastic fastening ring formed into a snap ring which connects a tube fitted into the pipe and prevents the separation of the tube. The stop collar closely adheres to the vertical adhesion units by fastening the nut members. An operator determines whether the stop collar is rotated or not and decides whether the nut members have to be fastened or not. |
