ABSTRACT:
A threadless coupling for pressurized systems includes, in one form, a nut member and a mating member. The nut member, in one embodiment, has a first axial end for attachment to the pressure sensitive control, a second axial end configured for engagement with the mating member, and a housing extending between the first axial end and the second axial end. The housing includes a pair of openings spaced 180.degree. apart and configured for locking engagement with a pair of retaining tabs extending from an outer surface of the mating member. Each housing opening includes a step surface and a seating surface. During assembly, the mating member retaining tabs are positioned 90.degree. out of alignment with the housing openings. A portion of the mating member including the retaining tabs is then inserted into the nut member. When the retaining tabs are axially aligned with the housing openings, the nut member is turned 90.degree. so that the housing openings are aligned with the retaining tabs. Each mating member retaining tab engages a corresponding seating surface and step surface of the respective housing opening so that relative axial and rotational movement of the nut member and mating member is prevented.
