Abstract

A pipe system includes a tubular body having an axis, a bore extending in an axial direction, a tubular body retainer groove formed in the bore, and a tubular body exterior. Retainers are configured to be mounted in the tubular body retainer groove only from the bore of the tubular body. In one version, the retainers cannot be installed in the tubular body retainer groove from the exterior of the tubular body. The retainers are configured to be circumferentially spaced apart from each other with respect to the axis. In addition, a pipe having a pipe exterior with a pipe retainer groove is configured to receive the retainers to form a pipe assembly.
