A male adaptor is provided with a nose for penetrating into a housing of the female connector. A septum is disposed over the nose of the male adaptor to maintain a seal with the female connector during coupling and uncoupling. Upon coupling, the septum dilates to allow the nose to pass through. The female connector may have a septum that also dilates to allow penetration of the nose of the male adaptor. Alternatively, the septum of the female connector may be retractable under the force of the nose of the male adaptor.

What is claimed is: 1. A closed system connector assembly comprising a male adaptor including a first housing having a projecting nose and a passage extending centrally therethrough, a locking ring mounted concentrically about said nose, and a first septum mounted on said nose and including a disk shaped body sealing over said passage and a tubular sleeve extending over said nose, said disk shaped body having a swabable surface flush with an end of said locking ring; and a female connector including a second housing having an external thread for threading into said locking ring of said male adaptor and being of an internal diameter to receive said nose of said male adaptor therein, a tubular member disposed concentrically within said second housing and defining a passage therethrough, and a second septum mounted on said tubular member and having a swabable surface flush with an end of said second housing. 2. A closed system connector assembly as set forth in claim 1 wherein said first septum includes a centrally disposed slit whereby upon penetration of said nose of said male adaptor into said second housing of said female connector, said body of said first septum dilates about said nose and said housing of said female connector pushes said dilated body along said nose to a retracted position. 3. A closed system connector assembly as set forth in claim 2 wherein said tubular sleeve of said first septum is resiliently collapsible during movement of said dilated body along said nose to a said retracted position whereby upon removal of said nose from said female connector said sleeve extends to return said dilated body over said passage in said tubular member. 4. A closed system connector assembly as set forth in claim 3 wherein said tubular sleeve of said first septum includes an internal flange at one end and said nose has an annular groove receiving said flange therein. 5. A closed system connector assembly as set forth in claim 1 wherein said female connector includes a segmented sleeve mounted on and projecting from said tubular member, said segmented sleeve having said second septum mounted thereon. 6. A closed system connector as set forth in claim 5 wherein said second septum has a bulbous portion extending into said segmented sleeve and a centrally disposed slit in said bulbous portion. 7. A closed system connector as set forth in claim 1 wherein said second septum has a slit disposed centrally thereof. 8. A closed system connector assembly comprising a male adaptor including a first housing having a projecting nose and a passage extending centrally therethrough, a locking ring mounted concentrically about said nose, and a first septum mounted on said nose and including a disk shaped body sealing over said passage and a tubular sleeve extending over said nose, said disk shaped body having a swabable surface coplanar with an end of said locking ring; and a female connector including a tubular housing for securement within a said locking ring of said male adaptor and having an internal diameter to receive a said nose of said male adaptor therein, a tubular member disposed concentrically within said tubular housing and defining a passage therethrough, and a second septum mounted on said tubular member and having a swabable surface coplanar with an end of said tubular housing. 9. A closed system connector assembly as set forth in claim 8 wherein said first septum includes a centrally disposed slit whereby upon penetration of said nose of said male adaptor into said tubular housing of said female connector, said body of said first septum dilates about said nose and said tubular housing of said female connector pushes said dilated body along said nose to a retracted position. 10. A closed system connector assembly as set forth in claim 9 wherein said tubular sleeve of said first septum is resiliently collapsible during movement of said dilated body along said nose to said retracted position whereby upon removal of said nose from said female connector said sleeve extends to return said dilated body over said passage in said tubular member. 11. A closed system connector assembly as set forth in claim 10 wherein said tubular sleeve of said first septum includes an internal flange at one end and said nose has an annular groove receiving said flange therein. 12. A closed system connector assembly as set forth in claim 8 wherein said female connector includes a segmented sleeve mounted on and projecting from said tubular member, said segmented sleeve having said second septum mounted thereon. 13. A closed system connector as set forth in claim 12 wherein said second septum has a bulbous portion extending into said segmented sleeve and a centrally disposed slit in said bulbous portion. 14. A closed system connector as set forth in claim 8 wherein said female connector includes a hollow needle disposed concentrically in said tubular member and said second septum is disposed in one end of said tubular member. 15. A closed system connector as set forth in claim 14 wherein said second septum has a silt disposed centrally thereof.
