Abstract
A coupling segment can comprise an arcuate central portion defining a first end, a second end, a first axial side, and a second axial side; a first end portion defining a shank and a bend, the shank extending from the first end of the arcuate central portion proximate the first axial side, the bend extending from the shank towards the second axial side, the bend defining a proximal end coupled to the shank and a distal end distal from the shank, the bend defining an engagement surface and a bottom surface opposite the engagement surface, the bottom surface lying in a plane, wherein the bottom surface faces away from the coupling segment such that the plane does not intersect the coupling segment; and a second end portion extending from the second end of the arcuate central portion, the second end portion defining an opening.
