1. A quick installation pipe coupling configured for connecting pipe ends, comprising:
a plurality of housing segments, each housing segment comprising radially inwardly projecting arcuate engaging shoulders that are configured for engaging pipe ends;
one or more tightenable connection members for connecting the housing segments with each other while surrounding a central space for insertion of said pipe ends; and
a gasket that is received into an annular channel that is defined by the housing segments in between the arcuate engaging shoulders and that is configured to engage sealing on said pipe ends upon tightening of the one or more connection members,
wherein the coupling further comprises a supporting barrier ring that is located between the gasket and a bottom wall of the annular channel that is defined by the housing segments in between the arcuate engaging shoulders,
wherein the supporting barrier ring extends as a protective barrier circumferentially around an outer surface of the gasket, and
wherein the supporting barrier ring is dimensioned and configured to support the housing segments spaced-apart in a pre-assembled ready for installation state with their arcuate engaging shoulders delimiting insertion openings towards the central space that are larger than cross-sectional dimensions of said pipe ends before tightening of the one or more connection members.
