PURPOSE: A chain link is provided to prevent corrosion of the chain of a sludge collector by making the chain link body of plastic material, and to assemble and disassemble the chain link conveniently by modifying the combination structure at low cost. CONSTITUTION: An assembling guide part(7) is protruded in a through hole(6), and engaged with an assembling protrusion(14) of a connecting pin(2) in a rear part(4). The connecting pin has a small cylindrical part(13) near the end of a pin body(12), and the assembling protrusion formed radially in the cylindrical part. The assembling guide part is protruded around the end of the through hole, and a guide groove is formed. An inclined surface is formed from the guide groove, and a settling groove is formed around the guide groove. Corrosion is prevented by manufacturing the chain link with plastic, and assembling or disassembling is convenient with modifying the structure.
