Abstract
Embodiments of a retaining ring for a pipe joint assembly comprise a unitary, ring-shaped body having radially inner and outer surfaces and axially inner and outer surfaces, wherein the radially inner surface is provided with a gripping segment comprising one or more fins, with each of the fins extending radially inwardly. Embodiments further include a wing formed therewith, extending radially outwardly from the radial outer surface to the radially outermost surface. In various embodiments, the retaining ring can be split.

A shoe gland retaining ring for a fitting, comprising:
- a unitary, ring-shaped body having radially inner and outer surfaces and axially inner and outer surfaces, wherein the radially inner surface is provided with a plurality of internal fins spaced axially apart along the radially inner surface, each of the plurality of internal fins extending radially inwardly when uncompressed, and wherein the body includes first and second circumferential end points forming a split in the body;
- and
- a wing extending radially outwardly from the radial outer surface between the axially inner and outer surfaces, wherein the radial outer surface is formed with an interior ridge extending axially from the axially inner surface to the wing, and wherein the wing includes an intermediate surface extending radially and axially outwardly from the interior ridge to a radially outermost surface of the radial outer surface.
