A fluid flow connector including a housing assembly, having a first end and a second end arranged along a common longitudinal axis, and a resilient fluid flow conduit member having a forward end, disposed alongside the first end of the housing assembly, formed with a selectably closable slit and with at least one side opening. The resilient fluid flow conduit member is positioned in a closed position wherein the slit is closed but the at least one side opening is open and in an open position, allowing the slit to open and leaving the at least one side opening open, whereby when the resilient fluid flow conduit member is in the open position, the selectably closable slit and the at least one side opening each provide a fluid flow pathway between an interior of the resilient fluid flow conduit member and the first end of the housing assembly.

1. A fluid flow connector comprising: a housing assembly having a first end and a second end arranged along a common longitudinal axis;a forward conduit and actuator element at least partially disposed within said housing assembly, said forward conduit and actuator element having a forward edge;a resilient fluid flow conduit sealing and biasing element locked within said forward conduit and actuator element, said resilient fluid flow conduit sealing and biasing element having a forward end positioned alongside said forward edge, said forward end being formed with a selectably closable slit extending along said longitudinal axis; anda rigid fluid flow conduit member disposed within said resilient fluid flow conduit sealing and biasing element,said forward conduit and actuator element and said resilient fluid flow conduit sealing and biasing element being positionable in a forward position wherein said selectably closable slit is closed; andsaid forward conduit and actuator element and said resilient fluid flow conduit sealing and biasing element being positionable in a rearward position, wherein said rigid fluid flow conduit member at least partially extends through said selectably closable slit causing said selectably closable slit to open and whereinsaid resilient fluid flow conduit sealing and biasing element is formed with an elongate bore and a forward end wall having a rearwardly facing surface, said slit being formed within said forward end wall;said forward conduit and actuator element is formed with an interior bore and a forwardly facing aperture; andwhen said forward conduit and actuator element and said resilient fluid flow conduit sealing and biasing element are positioned in said rearward position, said rigid fluid flow conduit member extends through said slit, and at least partially extends through said forwardly facing aperture, thereby stretchingly displacing said forward end wall forwardly and radially outward from said slit to a longitudinal orientation, tightly and circumferentially disposed between an exterior surface of said rigid fluid flow conduit member and said aperture, thereby unsealing said rigid fluid flow conduit member. 2. A fluid flow connector according to claim 1 and wherein said forward conduit and actuator element is arranged for displacement between said forward position and said rearward position along said common longitudinal axis. 3. A fluid flow connector according to claim 1 and wherein said resilient fluid flow conduit sealing and biasing element is arranged for partial displacement between said forward position and said rearward position along said common longitudinal axis. 4. A fluid flow connector according to claim 1 and wherein said first end is an internally-threaded end and said second end is an externally-threaded end. 5. A fluid flow connector according to claim 1 and wherein when said forward conduit and actuator element and said resilient fluid flow conduit sealing and biasing element are positioned in said rearward position, said forward conduit and actuator element is engaged by a displacement actuator and said rigid fluid flow conduit member at least partially extends through said selectably closable slit, thereby opening said selectably closable slit. 6. A fluid flow connector according to claim 5 and wherein when said forward conduit and actuator element and said resilient fluid flow conduit sealing and biasing element are positioned in said forward position, said forward conduit and actuator element is not engaged by said displacement actuator and said selectably closable slit is closed. 7. A fluid flow connector according to claim 1 and wherein said housing assembly also includes a rearward conduit which extends forwardly from said second end along said axis. 8. A fluid flow connector according to claim 7 and wherein said rigid fluid flow conduit member is integrally formed within said housing assembly and extends forwardly from said rearward conduit. 9. A fluid flow connector according to claim 1 and wherein said resilient fluid flow conduit sealing and biasing element is formed with a selectably compressible accordion type rearward portion disposed rearwardly of said elongate bore, said selectably compressible accordion type rearward portion defining an inner volume, communicating with said elongate bore. 10. A fluid flow connector according to claim 9 and wherein when said forward conduit and actuator element and said resilient fluid flow conduit sealing and biasing element are positioned in said rearward position and said forward conduit and actuator element is engaged by a displacement actuator, said selectably compressible accordion type rearward portion is rearwardly compressed against a forwardly facing circumferential surface of said housing assembly. 11. A fluid flow connector according to claim 1 and wherein said forward conduit and actuator element is arranged to be displaced rearwardly from said forward position to said rearward position along said axis by engagement of said forward conduit and actuator element by a rearwardly facing end of an external conduit. 12. A fluid flow connector according to claim 11 and wherein: said first end is an internally-threaded end; andsaid engagement of said external conduit with said forward conduit and actuator element is via said internally-threaded end. 13. A fluid flow connector according to claim 1 and wherein said resilient fluid flow conduit sealing and biasing element includes a generally elongate portion having an elongate bore formed therewithin along said axis, said elongate bore including an integrally formed interior facing sealing ring. 14. A fluid flow connector according to claim 13 and wherein said rigid fluid flow conduit member is slidably and sealingly disposed within said elongate bore in engagement with said sealing ring. 15. A fluid flow connector according to claim 13 and wherein said sealing ring and an exterior surface of said rigid fluid flow conduit member are in slidable sealing engagement. 16. A fluid flow connector according to claim 13 and wherein: said housing assembly also includes a rearward conduit which extends forwardly from said second end along said axis;said resilient fluid flow conduit sealing and biasing element is formed with a forward end wall having a rearwardly facing surface, said slit being formed within said forward end wall; andsaid fluid flow connector maintains a pressurized fluid seal for pressurized fluid in said rearward conduit, said rigid fluid flow conduit member, and a volume inside said resilient fluid flow conduit sealing and biasing element forward of said sealing ring, said pressurized fluid seal being provided by said sealing ring and by said rearwardly facing surface of said forward end wall. 17. A fluid flow connector according to claim 1 and wherein: said housing assembly also includes a rearward conduit which extends forwardly from said second end along said axis;said forward conduit and actuator element is formed with an interior bore and a forwardly facing aperture;said forward conduit and actuator element is arranged to be displaced rearwardly from said forward position to said rearward position along said axis by engagement of said forward conduit and actuator element by a rearwardly facing end of an external conduit; andwhen said forward conduit and actuator element and said resilient fluid flow conduit sealing and biasing element are in said rearward position, a fluid flow connection is open for fluid supplied via said rearward conduit and said rigid fluid flow conduit member to said external conduit via said slit and said aperture, wherein a volume of said fluid flow connection does not substantially change upon opening or closing of said fluid flow connection, thus providing a generally neutral fluid displacement characteristic.
