Patent ID: 8220840

Claim:
An apparatus for use in diving, the apparatus having a flexible hose interface connection that resists inadvertent demating of compressively engaged overlapping tubular connections, the interface connection comprising: a first inner connector residing partially within a second outer connector and a positive locking ring comprising: a C-shaped annular member made of a material that is resistant to deformation; and a pair of unlocking pins at respective opposed terminal locations and extending radially through openings in said second outer connector to facilitate external access to said positive locking ring to demate said first inner connector and said second outer connector; wherein said positive locking ring being made integral to said outer connector by being bonded to an inner mating surface of said second outer connector during molding of the said second outer connector, said positive locking ring having an inner surface that is fully exposed for compressively engaging an outer mating surface of said first inner connector to prevent inadvertent demating of said first inner connector and said second outer connector tubular connectors; and wherein the positive locking ring C-shaped annular member is substantially underneath the second outer connector when the first inner connector and the second outer connector are mated, wherein said C-shaped annular member is compressively engaged with said outer mating surface of said first inner connector with a sufficient force to prevent inadvertent axial separation of said first inner connector and said second outer connector, but without preventing relative rotation of said first inner connector and said second outer connector.
