1. A conduit coupling assembly configured to clamp to a fluid conduit oriented about a longitudinal axis comprising:
an arcuate first clamp ring having a first longitudinal edge and a second longitudinal edge;
a first connecting assembly configured to tighten said first clamp ring to said fluid conduit from a non-actuated position to a tightened position;
an arcuate first gasket configured to be positioned radially between said first clamp ring and said fluid conduit;
said first clamp ring comprising a first inner surface radially facing a first outer surface of said first gasket;
said first clamp ring comprising an inwardly extending annular first side wall;
an arcuate second clamp ring having a first longitudinal edge and a second longitudinal edge;
a second connecting assembly configured to tighten said second clamp ring to said fluid conduit from a non-actuated position to a tightened position;
an arcuate second gasket configured to be positioned radially between said second clamp ring and said fluid conduit;
an arcuate middle ring configured to extend axially between said first clamp ring and said second clamp ring;
said middle ring comprising an outwardly extending annular first flange;
at least a portion of said first flange of said middle ring disposed axially between and radially overlapping at least a portion of said first side wall of said first clamp ring and at least a portion of an annular first side surface of said first gasket;
said first annular flange of said middle ring comprising an axially extending first retention rim;
said first retention rim of said first annular flange of said middle ring axially overlapping and disposed radially between a first retained portion of said first outer surface of said first gasket and a first opposed portion of said first inner surface of said first clamp ring; and
said first retention rim of said first annular flange of said middle ring and said first retained portion of said first outer surface of said first gasket forming a gasket retaining element restraining radial movement of said first side surface of said first gasket relative to said first flange of said middle ring.
