ABSTRACT:
The present invention relates to an alternative pipe coupling apparatus, to conventional tapered screw threads usually used to join ends of pipe sections to fixtures. The invention utilizes a bayonet style interlocking arrangement having a male element and a female element which join together and are opposingly biased against one another by a spring-like retaining ring to ensure an appropriate rigid and leak-proof connection between two elements.
