What is claimed is: 1. A closure for a connector having a housing, said housing having an opening portion opened to the outside, a connecting port connected to a tube and a flow channel space that allows flow of liquid through said connecting port, said closure comprising: a valve member for attachment to said opening portion and for allowing a liquid from outside to flow into said flow channel space after opening of said valve member, said valve member comprising a main body portion that seals said opening portion liquid tight and can be moved to the side of said flow channel space under the pressing force from the outside, said main body portion having an outer surface facing the outside and an inner surface facing the flow channel space while said opening portion is blocked liquid tight; a supporting portion connected to said main body portion and engaged to said housing, the supporting portion having an elastic force that acts on said main body portion when said main body portion moves to the side of said flow channel space under the pressing force from the outside; and an inner slit formed in said main body portion from said inner surface toward said outer surface, the inner slit being spaced from the outer surface, wherein a connecting surface formed on said outer surface of the main body portion is connected to said flow channel space when said main body portion is pressed into the side of said flow channel space under the pressing force from outside. 2. The closure according to claim 1 wherein said inner slit is formed to bisect said inner surface. 3. The closure according to claim 1 wherein an outer slit is formed in said main body portion extending from said outer surface toward said inner surface. 4. The closure according to claim 1, wherein the closure is a part of a Luer connector. 5. The closure according to claim 4, wherein the closure is attached to a valve unit. 6. The closure according to claim 5, wherein the valve unit is a three-way valve unit. 7. A connector comprising: a housing having an opening portion opened to the outside, a connecting port connected to a rube and a flow channel space that allows flow of liquid through said connecting port; a valve member for attachment to said opening portion and for allowing a liquid from outside to flow into said flow channel space after opening of said valve member, said valve member comprising a main body portion that seals said opening portion liquid tight and can be moved to the side of said flow channel space under the pressing force from the outside, said main body portion having an outer surface facing the outside and an inner surface facing the flow channel space while said opening portion is blocked liquid tight; a supporting portion connected to said main body portion and engaged to said housing, the supporting portion having an elastic force that acts on said main body portion when said main body portion moves to the side of said flow channel space under the pressing force from the outside; and an inner slit formed in said main body portion from said inner surface toward said outer surface, the inner slit being spaced from the outer surface, wherein a connecting surface formed on said outer surface of said main body portion is connected to said flow channel space when said main body portion is pressed into the side of said flow channel space under the pressing force from outside. 8. The connector according to claim 7 wherein said inner slit is formed to bisect said inner surface. 9. The connector according to claim 7 wherein an outer slit is formed in said main body portion extending from said outer surface toward said inner surface. 10. The connector according to claim 7, wherein the connector is a Luer connector. 11. The connector according to claim 7, wherein the connector is a valve unit. 12. The connector according to claim 11, wherein the valve unit is a three-way valve unit. 13. A fluid through-flow connector comprising: at least one connection port, said connection port comprising a connection port housing having an inner surface defining an inner volume and an outer surface; a sealing member having an inner portion extending within said inner volume and at least one outer portion extending externally of said housing, wherein said inner portion includes an inner slit extending from a lower surface of said inner portion, the inner slit being spaced from the outer surface, wherein said sealing member is of an elastically deformable material, wherein said sealing member is arranged such that it is deformable from a first closed state in which said sealing member is arranged in a fluid sealing configuration to a second open state in which said sealing member is arranged in a fluid non-sealing configuration and in which said inner portion is displaced into said inner volume and in which said at least one outer portion exerts a restoring force on said inner portion urging said inner portion to return to said first closed state, said deformation from said first closed state to said second open state being caused by the making of a connection to said connection port. 14. The connector according to claim 13 wherein said inner slit extends only partially between said lower surface and an upper surface of said sealing member. 15. The connector according to claim 14 wherein said sealing member further includes at least one outer slit extending from an upper surface of said inner portion. 16. The connector according to claim 15 wherein each of said inner slit and said at least one outer slit extend only partially between said upper surface and said lower surface. 17. The connector according to claim 13 wherein said sealing member comprises two said outer portions. 18. The connector according to claim 13 wherein said sealing member is secured to said housing by a cover. 19. The connector according to claim 13 wherein said inner surface comprises a substantially cylindrical upper region and a frusto-conical lower region. 20. The connector according to claim 13 wherein the connector is a Luer connector. 21. The connector according to claim 20 wherein the Luer connector is part of a valve system.
