ABSTRACT A system for connecting an annular, rigid component to an opening in a flexible sheet material is disclosed. The system includes a boss molded around the opening in the sheet material and a groove around the component, sized to accommodate the boss. An annular keeper engages the boss circumferentially under hoop stress and compresses the boss against the component. A ledge on the component engages the keeper to retain it in operating position. In preferred embodiments, installation is assisted with a tapered face leading to the ledge, to produce elastic deformation of the keeper to the extent that it will pass over the boss and then snap back once past the ledge.
