ABSTRACT:
A connection system for sealingly interconnecting components of a high pressure fluid flow system, for example, an automobile engine air intake. The system can include a conduit defining a groove that is locked in a corresponding groove defined by a component, for example, an engine intake. An interlock ring is placed in the conduit groove. A clamp is placed over the interlock ring, however, the clamp and ring can be an integral component. When tightened, the clamp forces the ring into the conduit groove, which presses the conduit into sealing and/or locking engagement with the component groove.
