Patent ID: 8449528

Claim:
A connector for coupling a medical fluid supply tube to the head of a catheter device having a circular hub having a generally horizontal top surface that extends radially outward over a generally vertical side surface to define a circumferential recess in the side surface of the circular hub, the connector comprising: a resilient assembly including cantilevered springs, wherein each cantilevered spring has at least one arm, each arm having a first end, a central section, and a second end that is joined to a central support; and a plurality of release buttons extending from the resilient assembly, each release button having a first portion including a finger contact zone and a second portion including a catch, the catch configured to releasably engage a circumferential recess defined in a side surface of the circular hub, wherein the connector is coupled to the circular hub having a generally horizontal top surface that extends radially outward over the generally vertical side surface to define a circumferential recess by positioning the connector on the hub and depressing the connector until the catches engage the circumferential recess such that the connector is free to rotate completely about the circular hub and the connector is decoupled from the hub by pressing the release buttons radially inward to reversibly displace the cantilevered springs thereby moving the respective catches radially outward to disengage them from the circumferential recess.
