The present invention is a drain pipe coupling to sealably couple an insert pipe with an existing drain pipe, the drain pipe coupling comprises of an elastic tubular body concentrically positioned over the insert pipe and the existing drain pipe; a first and a second retaining rings having a toroid body which is connected to a tightening tool. Turning a screw on tightening tool causes an increase or decrease of diameter of the retaining ring and deforming the elastic tubular body to sealably contact with inner surfaces of the insert pipe and the existing drain pipe.
