Abstract
Disclosed herein is a coupler for joining lengths of corrugated pipe including those provided with radial end flanges. The coupler is comprised of two semicircular sections joined at the ends thereof about the juncture of the pipe lengths. Each section has a channeled central portion which is disposed over the ends of the abutting pipe lengths and about the radial end flanges, when provided, and corrugated lateral portions which fit over and mate with the corrugations in the pipe lengths adjacent the ends thereof, thereby forming a strong and durable coupling for the abutting pipe lengths.
