1. A method of securing facing end portions of pipe elements together in end-to-end relationship, wherein said end portions of said pipe elements have an outer surface of substantially cylindrical profile, said method comprising the steps of:

  • providing a pipe coupling having a plurality of coupling segments attached to one another end-to-end surrounding a central space, said coupling segments having arcuate surfaces adapted to interface with the outer surfaces of said pipes;

    inserting said end portions of said pipe elements into said central space; and

    deforming said coupling segments so as to conform the curvature of said arcuate surfaces of said coupling segments to said outer surfaces of said pipe elements.
