Sterile coupling comprising a male and a female connector, each provided with a membrane device comprising a membrane surface covered with an adhesive at the exterior surface. When the connectors are brought into operation, the adhesive surface are contacted to form a bonded surface. Then, a hole is generated through the bonded surface and the sterile portions of the devices are brought into cooperations. The hole is formed by a rupture member arranged in one of the connectors. After rupturing, the membrane devices retract to a space formed between the cylindrical bodies of the connectors.

The invention claimed is: 1. A sterile coupling comprising a male connector having a first membrane device covering a first end and a second end adapted to be connected to a sterile region, said first membrane device being fixedly connected to said male connector adjacent said second end of said male connector and a female connector having a second membrane device covering a first end and a second end adapted to be connected to a sterile region, each membrane device having an exterior surface comprising an adhesive material and an interior surface facing a sterile area, so that the adhesive materials form a bonded membrane surface when the two connectors are joined, and a rupture device mounted within said female connector, which ruptures the bonded membrane surface inside said female connector for forming said sterile coupling. 2. The sterile coupling according to claim 1, wherein said second membrane device of said female connector is fixedly connected to said female connector adjacent said first end of said female connector and has a cup-shape extending into said female connector. 3. The sterile coupling according to claim 1, wherein said male and female connectors each comprises a cylindrical body, forming a space therebetween during cooperation, said space accommodating the membrane devices after rupturing and said membrane devices expanding in said space to fix said male and female connectors in relation to each other. 4. The sterile coupling according to claim 1, wherein said interior surface of said second membrane device of said female connector comprises a weakening line for guiding the rupture and wherein said rupture device comprises at least one prominence which engages said weakening line. 5. The sterile coupling according to claim 1, wherein the first membrane device of the male connector is pre-stretched before use. 6. The sterile coupling according to claim 1, wherein each said adhesive material is covered by a tape before use, which is removed just before use. 7. The sterile coupling according to claim 1, wherein an interior surface of said male connector comprises a shoulder and an exterior surface of said rupture device comprises a complementary shoulder for interconnection thereof after the rupture of said membrane devices. 8. The sterile coupling according to claim 2 characterized in that one or both of the membrane devices comprise grooves for letting out surplus air from an area of adhesive materials. 9. The sterile coupling according to claim 2, characterized in that said male and female connectors each comprises a cylindrical body, forming a space therebetween during cooperation, said space accommodating the membrane devices after rupturing and said membrane devices expanding in said space to fix said male and female connectors in relation to each other. 10. The sterile coupling according to claim 2, wherein said interior surface of said second membrane device of said female connector comprises a weakening line for guiding the rupture and wherein said rupture device comprises at least one prominence which engages said weakening line. 11. The sterile coupling according to claim 3, wherein said interior surface of said second membrane device of said female connector comprises a weakening line for guiding the rupture and wherein said rupture device comprises at least one prominence which engages said weakening line. 12. The sterile coupling according to claim 2, wherein the first membrane device of the male connector is pre-stretched before use. 13. The sterile coupling according to claim 3, wherein the first membrane device of the male connector is pre-stretched before use. 14. The sterile coupling according to claim 4, wherein the first membrane device of the male connector is pre-stretched before use. 15. The sterile coupling according to claim 2, wherein each said adhesive material is covered by a tape before use, which is removed just before use and wherein said tape in said cup-shaped membrane device has a flap extending out of said cup-shaped membrane device. 16. The sterile coupling according to claim 3, wherein each said adhesive material is covered by a tape before use, which is removed just before use. 17. The sterile coupling according to claim 4, wherein each said adhesive material is covered by a tape before use, which is removed just before use. 18. The sterile coupling according to claim 5, wherein each said adhesive material is covered by a tape before use, which is removed just before use. 19. The sterile coupling according to claim 2, wherein an interior surface of said male connector comprises a shoulder and an exterior surface of said rupture device comprises a complementary shoulder for interconnection thereof after the rupture of said membrane devices. 20. The sterile coupling according to claim 3, wherein an interior surface of said male connector comprises a shoulder and an exterior surface of said rupture device comprises a complementary shoulder for interconnection thereof after the rupture of said membrane devices. 21. The sterile coupling according to claim 1 wherein said first membrane device comprises an enlargement shoulder for securing said first membrane device under tension to said male connector. 22. The sterile coupling according to claim 21 further comprising a tensioning sleeve adapted to engage said enlargement shoulder and said male connector. 23. The sterile coupling according to claim 22 wherein said tensioning sleeve further comprises a plurality of hooks for engaging said enlargement shoulder and a shoulder adapted to engage a groove in said male connector whereby said first membrane device is stretched over said male connector. 24. The sterile coupling according to claim 3 wherein said male connector is tapered towards said first end thereof. 25. The sterile coupling according to claim 2 wherein said second membrane device further comprises a shoulder adapted to engage said first end of said female connector. 26. The sterile coupling according to claim 25 wherein said first end of said female connector further comprises a groove that receives said shoulder of said second membrane. 27. The sterile coupling according to claim 1 wherein said second membrane device is secured to said female connector at said first end thereof, and a longitudinal portion of said second membrane device extends into said female connector along an interior wall of said female connector, and said longitudinal portion is folded back on itself such that said adhesive material of said second membrane device is adjacent said first end of said female connector. 28. The sterile coupling according to claim 2 wherein said adhesive material of said second membrane is domed towards said first end of said female connector.
