A coupler joint (10) which includes a hollow cylindrical portion (11) opened at its opposite ends and a flange (12) disposed along the circumference of the cylindrical portion (11) near the longitudinal center to be interposed between a dialyzer connector (21) and a coupler (30) so as to be in liquid tight engagement; one side of the flange (12) of the coupler joint10being in liquid-tight abutment with an opening (22) of the connector (21) of the dialyzer (20), and the other side of the flange (12) being in liquid-tight abutment with the a seal surface31of the coupler (30). Accordingly, a dialysis solution does not collect in a concave groove (32) which accommodates an O-ring (40) of the coupler (30), and proliferation of bacteria can be prevented.
