A connector to fluidly connect ends of conduits. The connector comprises a connector tubular body which includes a wall, a stopper and one or more conduit-retainer. The wall has an inner and outer surface, with a first conduit-receiving section and a second conduit-receiving section being defined at a first and second ends of the wall, respectively. Each of the first and second conduit-receiving sections are configured to internally and concentrically receive an end portion of a conduit. The stopper extends radially inward from the inner surface of the wall, between the first and the second conduit-receiving sections and is provided with a seal on each side of the stopper adapted to restrict fluid leakage when conduits are installed in the connection. The at least one conduit-retainer extends inwardly from the inner surface of the wall. The at least one conduit-retainer being lockably engageable with a conduit being received.
