To provide a joint member used in a leak test which can be easily replaced and has improved workability.SOLUTION: A joint member 1 which is mounted on a flow path of a drain pipe and performs a leak test includes a joint body 2 and an insertion member 3. The joint body 2 has an inflow port 21 formed at the upstream end, an outflow port 22 formed at the downstream end, and an attachment port 23 formed at the side surface. The insertion member 3 inserted from the attachment port 23 includes a plurality of replaceable functional units, and can be replaced depending on the application. A closing portion 4 is a functional portion which is attached to the insertion member 3 and closes the drainage flow path, and is attached at the time of a leak test. A backflow prevention valve is a functional part which is attached to the insertion member 3 after the end of the leak test, and gives the joint member 1 a function as a backflow prevention device.SELECTED DRAWING: Figure 1 【課題】漏洩試験に用いられる継手部材において、部材の交換を容易とし、施工性を向上させた継手部材を提供する。【解決手段】排水配管の流路上に取り付けられて、漏洩試験を行う継手部材１は、継手本体２と挿入部材３とから構成されている。継手本体２は、上流側端部に形成された流入口２１と、下流側端部に形成された流出口２２と、側面に形成された取付口２３とを有する。取付口２３より挿入される挿入部材３は、交換可能な複数の機能部を備えており、用途に応じて交換可能となっている。閉塞部４は、挿入部材３に取り付けられて排水流路を閉塞する機能部であり、漏洩試験時に取り付けられる。逆流防止弁は、漏洩試験終了後に挿入部材３に取り付けられる機能部であり、継手部材１に逆流防止装置としての機能を付与する。【選択図】図１
