Tube coupling.

摘要

A tube coupling adapted particularly for medical use includes three parts, namely a female tubular element 52, a male tubular element 50, and an intermediate ring 100 carrying at least one longitudinally extending latching arm 110. The ring is dimensioned to snap-fit into an external annular groove 90 on either the male or female element and the latching arm has an inwardly-extending hook portion 112 which can engage a flange 58 on the female or the male element as the case may be. This engagement holds these two elements together in an axial direction and allows them to rotate freely relatively to one another.
