ABSTRACT:
Connector connects two annular objects face-to-face. It may be used as a hose end coupling that connects two flanged hose ends end-to-end. It includes two components of the same configuration that connect directly to one another. Each a hose end flange preferably has a tapered back face and an O-ring seal fitted in a groove in the end face to engage an O-ring seal on the end face on the mating component. To hold the two end flanges together, two connector components of the same configuration are mounted on the respective end flanges. Each includes two part annular retainers that engage over the hose end flanges and urge them together. The web joining the two retainers has an offset section with teeth that engage similar teeth on the other connector component. The coupling is intended for use in breathing gas supply systems such as are used in medical applications.
