1. A pipe coupler for connecting a pipe through a casing to a line comprising: a. a first coupler member having on one side thereof a vertical trackway with two open ends; b. a bore extending through said first coupler member for communicating said pipe to said line; c. a second coupler member having a plate formed thereon and adapted for sliding movement in said trackway through either open end thereof; and d. a stop formed on said plate to limit the movement of said plate through said trackway.

5. The method of attaching to a bore in a casing, at least one section of a two-section coupling of the type wherein the first section includes a nipple extending from a body and a trackway extending vertically on the opposite side of the body with a uniform width and breadth and a second section including a body having a uniform thickness plate integrally secured thereto with a stop formed at one end thereof including the steps of: a. assembling the first section onto the second section with the second section inverted to position the stop at the lower end thereof in supporting relation to the first section; b. attaching a handle to said second section for jointly manipulating said first and second section; c. lowering said sections into said casing; and d. manipulating the coupling to project the nipple through said bore in the casing.
