PURPOSE: A connector for a drain pipe is provided to smoothly flow sewage from a connection pipe to a main pipe by adding a resistance reducing ring between a rear circumference vertical plate and a front end part of the connection pipe. CONSTITUTION: A connector for a drain pipe comprises a connection pipe(1), a circumference recessed unit(2), an elastic fastening ring(3), a watertight pipe(4), a fixing nut(5), and a band clamp(6). The elastic fastening ring is bent in a process inserted to a penetration hole(101) and includes a flowing fastening circumference plate(32) fastened in inner circumference of the penetration hole by adhering to a front circumference plate(23) while being recovered after penetrating to the penetration hole. A front watertight plate(41) is formed to be adhered to outer circumference of the penetration hole in an outer side of circumference of the watertight pipe front side. The band clamp is mounted on a circumference recessed groove(12) and fixes a connection pipe(200) inside the rear of the connection pipe.
