Abstract
An improved fluid connector has a deformable axially outer ring with latches which retain a tube within a main body of the connection. The outer ring is oval in cross-section, with the latches extending along surfaces spaced across the minor diameter of the oval. Connection portions connect the outer ring to a main body of the connector. The connection portions extend from locations spaced across the major diameter of the oval shape. An upset portion of the tube deforms the latches radially outwardly upon insertion. A removal force may be directed radially inwardly of the outer ring at locations adjacent to the connection portions to cause the latches to bow radially outwardly and allow the tube to be removed from the connector. The inventive connector bears the removal force on the relatively thicker connecting portions, and requires flexing in the relatively thinner outer ring.
