Abstract
A swivel type junction fitting for an endotracheal tube or the like formed of hollow cylindrical male and female members telescoped together, the female member having at one end a land surface and an adjacent annular groove together with an axially offset centering surface. The male member has at its tip an annular guide surface and a shallow annular ridge offset from the guide surface. The ridge has an interfering fit with respect to the land surface on the female member, and at least one of the members is molded or relatively soft resilient plastic so that when the members are pressed together the ridge clicks past the land surface and into permanent register with the groove with detent action, accompanied by movement of the guide surface into a position opposite the centering surface for relative swiveling of the members free of cocking or binding.
