Abstract

A preassembled mechanical pipe coupling for joining pipe elements in end-to-end relationship is disclosed. The coupling is formed from a plurality of interconnectable segments that are initially maintained in spaced apart relation. The segments have arcuate surfaces that project inwardly. Connection members in the form of lugs and fasteners are mounted on the segments. The connection members are adjustably tightenable for drawing the coupling segments together and forcing the arcuate surfaces into engagement with the outer surfaces of the pipe elements. Notches are formed at ends of the arcuate surfaces to provide clearance allowing the pipe elements to be inserted between the segments when they are in the pre-assembled, spaced apart configuration.
