A coupler for receiving a threaded male luer fitting in sealed relationship includes a housing having an attachment end, a conduit end opposite the attachment end and defining a central passageway for providing fluid communication between the luer fitting and a conduit. An arrangement is attached to the housing for establishing a sealed connection between a luer tip and the central passageway. The conduit end has a relatively larger diameter than the attachment end and defines a shoulder at a junction of the attachment end and the conduit end. A resilient member is disposed on the attachment end adjacent the shoulder for exerting an axially directed compressive force upon the male luer fitting as it is threadably engaged upon the attachment end.

The coupler as defined in claim 12 wherein said resilient member is a washer which circumscribes said attachment end. 14. The coupler as defined in claim 12 wherein said resilient member is a leaf spring. 15. The coupler as defined in claim 1 wherein said resilient member is fixed to said attachment end and to said shoulder. 16. The coupler as defined in claim 1 wherein said resilient member is retained in position on said attachment end between said threads and said shoulder and is thus prevented from axial movement relative to said housing. 17. The coupler as defined in claim 15 wherein said resilient member has a Durometer value selected to be sufficiently resilient for preventing movement of threads of the male luer fitting and said attachment end. 18. The coupler as defined in claim 1 wherein said diameters are configured so that said shoulder is externally located on said housing. 19. The coupler as defined in claim 17 wherein said Durometer value is approximately 60 Durometers. 20. The coupler as defined in claim 12 wherein said resilient member is fixed to said attachment end and to said shoulder. 21. The coupler as defined in claim 20 wherein said resilient member has a Durometer value selected to be sufficiently resilient for preventing relative movement of threads of the male luer fitting and said threads of said attachment end. 22. The coupler as defined in claim 12 wherein said resilient member is retained in position on said attachment end between said threads and said shoulder and is thus prevented from axial movement relative to said housing.
