PURPOSE: A pipe connector is provided to prevent the relative rotation of an insert to a body because a joining unit of the insert is formed into a square shape. CONSTITUTION: A pipe connector comprises a body, an insert(110), and first and second O-rings(120,130). The body comprises a flow path(100a) and a ring-shaped groove(100b). The flow path of the body is connected to a flow path of a first pipe. The ring-shaped groove is opened in a longitudinal direction. The insert comprises a joining unit and a pipe coupling unit. The joining unit is fitted into the ring-shaped groove. The pipe coupling unit is thread-coupled with a screw. The first and second O-rings are interposed among an internal surface, an external surface of the joining unit of the insert, and the body. Internal and external projections(104a,104b) are fitted into an internal O-ring groove and external O-ring groove(112b) of the joining unit of the insert.
