ABSTRACT:
A valve body containing a ball valve member and having a threaded portion on the outer surface of an end portion thereof is connected with a body cap having a flange integral therewith on the outside end, by screwing a cap nut having an annular rib on the inner surface of the outside end thereof on the threaded portion of the valve body. A split ring is inserted into the space between the body cap and the cap nut. The split ring consists of two divided ring elements. Each ring element is provided with a fitting projection to be fitted into an annular groove of the body cap, on the inner surface of the outside end, and a collar-like projection is provided on the outer surface of the inside end. Both ends of the inner surface of the fitting projection of the ring element are cut off at the corners. The body cap is connected with the valve body by pushing the annular rib of the cap nut against the collar-like projection of the split ring and screwing the cap nut onto the threaded portion of the valve body.
