Abstract

Abstract A rotatable coupling member for attachment to an end or between the ends of hose or tubing to be used in the conveyance of a fluid under pressure. The coupling member comprises a first body member having means disposed at one end thereof for attaching the first body member to a source of fluid and a substantially tubular shaped insert extending away from a second end thereof into an axially aligned receiving bore disposed at a first end of a second body member that provides a fluid interconnecting relationship to a second end of the second body member having means disposed thereat for attachment to a source of fluid. An annular retainment groove having a cross-sectional shape capable of being altered as a result of an axial compressive force being applied to the insert is disposed in the first body member insert outer wall. An annular retainment receiving groove is disposed in the inner wall of the receiving bore and is axially aligned with the insert retainment groove so that retainment means such as, for example, an arcuate shaped wire, originally disposed in the insert retainment groove, is caused to extend radially outwardly therefrom into the second body member retainment receiving groove as a result of axially compressing the insert to provide a rotatable, interlocked relationship between the first and second body members.
