A connector for medical tubing for liquid transfusion includes a short tubular male connector member made of thermally resistant corrosionproof materia; a short tubular female connector member made of thermally resistant corrosionproof material; and a fitting surface portion on the outer surface of an insertion end of the male connector, shaped in the male form and made of a material having a smaller thermal expansion coefficient than the material of a corresponding fitting surface portion on the inner surface of an insertion end of the female connector shaped in the female form. The fitting surface portion of the insertion end shaped in the male form, and the fitting surface portion of the insertion end shaped in the female form, are of relative sizes such as to permit the insertion ends to be connected to and separated from each other by shrink fit utilizing the difference between the thermal expansion coefficients thereof. A medical solution bag device using the connector is also disclosed. |
