The present invention relates to a dual pipe type pipe connector comprising: an inner socket having an outlet and an inlet so that an outlet part and an inlet pipe are mutually connected to communicate, wherein the outlet part is coupled to the outer surface of the inlet pipe; an outer socket penetrated by the outlet part and the inlet pipe, and fixed and coupled to the inner socket by surrounding the periphery of the inner socket; and a bush being coupled between the outer surface and inner surface of the outlet part with sealing, and installed not to relatively rotate against the inner socket. A latching protrusion protruding inside the outlet is formed on the inner circumferential surface of the outlet of the inner socket, multiple first groove parts are separately formed on the surface of the latching protrusion along the periphery of the inner circumferential surface, and multiple first insertion protrusions to be inserted into the first groove parts are formed on one longitudinal end surface of the bush. |
