Abstract
Abstract A two-piece retaining ring assembly axially secures a coupling nut to a tubular sleeve and includes a C-shaped retaining ring and a keeper, both formed from a non-metallic composite material. An annular groove is formed on the inside surface of the coupling nut for receiving the retaining ring. The width of the gap defined between the ends of the retaining ring is such to allow the retaining ring to be pulled apart enough slipped over the annular shoulder on the tubular member and resilient enough to spring back to be received in an annular groove formed on the inside of the coupling nut. A keeper is received in an annular space between retaining ring and the tubular member. A tab, formed on the keeper, is received in the gap between the ends of the retaining ring. Anti-rotation means are also provided to restrict rotation of the coupling nut with respect to the backshell. One end of the tubular member is formed with an annular shoulder having ratchet teeth. A leaf spring, attached to the inside of the coupling nut, is provided with one or more radially inwardly extending teeth having slopes which cooperate with the ratchet teeth formed on the annular shoulder of the tubular sleeve.
