ABSTRACT:
The disclosure is of a captured nut coupling particularly adapted to join two articles and to convey fluids between the joined articles. The coupling is a fastener comprising a split ring inner or male member and a solid retaining and locking outer or female member. The male and female members are locked together after the male member is connected to one of the articles to be joined. In one embodiment the inner male member bears an inner rib which rotatably engages a groove in one of the articles for connection and the outer female member includes a means for engaging the other article for connection.
