ABSTRACT OF THE DISCLOSURE A drain-cleaning implement having a plastic shell of two subshells snapped together using male and female mating means along abutting edges and having a snake coiled within the shell and exerting outward mating force on it. The male means are on projections extending from inwardly- projecting sidewall portions formed at intervals around the inside surface of one subshell, and such inside surface has substantially edge-free transitions between the inwardly projecting portions and positions therebetween to strengthen the shell with maximum mating force from the snake. Preferred embodiments have corner-free mating means. A stop ledge facilitates proper mounting of a rotatable handle.
