Abstract
Segmented pipe couplings are formed by two or more identical arcuate pipe coupling segments. Each end of each segment is matable to either end of each other segment. Each end has a tongue and a recess generally on opposite sides of a longitudinal central plane of the segment. The positioning of the tongue and recess is reversed with respect to the central plane at opposite ends of each segment. Each recess is slightly larger than the tongue to receive the tongue of an identical coupling. A double tongue-double recess interfit is formed when any coupling segment is coupled together with an identical coupling segment. Either end of any coupling segment can mate with either end of other coupling segment and form a proper connection between segments.
