ABSTRACT OF THE DISCLOSURE The present invention relates to a retainer gland for mechanical joint pipe and mechanical joint fittings. The gland includes a flat ring portion having a longitudinal axis with two substantially parallel faces perpendicular to the axis and an opening with a circular inner circumference. A circular rib portion extends generally axially from one face of the flat ring portion adjacent said inner circumference, the flat ring portion and the circular rib portion having a generally L-shaped radial cross section, wherein the retainer gland further comprises at least a first hinge arm extending generally axially from the other face of the flat ring portion and terminating in an outer end portion. The first hinge arm has a transverse hole through said outer end portion, the hole being coaxial with a hinge axis which is perpendicular to a plane containing the longitudinal axis of the flat ring portion. There is no axial protrusion from the other face of the flat ring portion that does not intersect said hinge axis.
