Beschreibung
Zusammenfassung:	Pipe coupling apparatus including a tubular female coupling structure and a tubular male coupling structure sized to fit within and mate with the female coupling structure, one coupling structure including a housing and a locking ring that is radially deformable within an annular supporting groove of the housing, the other coupling structure including a tapered surface for biasing the ring to vary its radius as the coupling structures are brought together and an annular locking groove for receiving the ring when it is aligned with the locking groove as the coupling structures are moved further together and the ring springs back toward its undeformed shape, one coupling structure carrying an annular seal to provide a fluid-tight seal between said coupling structures.
