PROBLEM TO BE SOLVED: To provide a drain collection pipe coupling capable of preventing a backflow of drain water to a horizontal branch pipe connection part and splashing-back of the drain water in a lower edge part of the horizontal branch pipe connection part.SOLUTION: The present invention relates to a drain collection pipe coupling 1 having vertical pipe connection parts 5 and 6 in an upper end part and a lower end part, and having a cylindrical coupling body 13 having horizontal branch pipe connection parts 11 and 12 on a side surface. A longitudinal rib for preventing a backflow of drain water 14 to the horizontal branch pipe connection parts 11 and 12, is integrally projected in a side part of the horizontal branch pipe connection parts 11 and 12 on an inner peripheral surface of the coupling body 13. A cylindrical eaves forming member having an eaves part 23 for preventing splashing-back of the drain water 14 in a lower edge part of the horizontal branch pipe connection part 12, is installed on the inside of the coupling body 13. A slit-like fitting part fitted-locked from above to the longitudinal rib, is provided in this eaves forming member.SELECTED DRAWING: Figure 1 【課題】横枝管接続部への排水の逆流や、横枝管接続部の下縁部での排水の跳ね返りを防止し得る排水集合管継手を提供する。【解決手段】上端部と下端部とに立管接続部５，６を有すると共に、側面に横枝管接続部１１，１２を有する筒状の継手本体１３を備えた排水集合管継手１に関する。継手本体１３の内周面における横枝管接続部１１，１２の側部に、横枝管接続部１１，１２への排水１４の逆流を防止するための縦リブを一体に突設する。継手本体１３の内部に、横枝管接続部１２の下縁部での排水１４の跳ね返りを防止するための庇部２３を備えた筒状の庇形成部材を設置する。この庇形成部材に、縦リブへ上方から嵌合係止されるスリット状嵌合部を設けるようにする。【選択図】図１
