Patent ID: 7571937

Claim:
A fluid coupling assembly for retaining a sealed joint, composing: a first member adapted to be connected to a first fluid conduit and having a first sealing surface, a radially projecting series of serrations and a first fastening configuration; and a second member adapted to be connected to a second fluid conduit, a second fastening configuration and enabling a second sealing surface to engage the first sealing surface, the second member has a plurality of annularly spaced axially cantilevered beams, each beam having at least one tooth of a configuration to engage the series of serrations, an operative engagement of the tooth and serrations enables a relative low force rotation during a sealing engagement of the first sealing surface and the second sealing surface and a relatively higher force resistance to rotation during disengagement the axially spaced cantilevered beams are spaced to position respective distal ends of the cantilevered beams to enable a visual conformation of engagement of an alignment of a tooth and the annular serrations between the spacing of the cantilevered beams.
