To provide a tube clamp preventing easy displacement of a compression protrusion.SOLUTION: A medical tube clamp 100 includes a first plate-like part 101 and a second plate-like part 102. The first plate-like part 101 includes a first compression protrusion 111. The second plate-like part 102 includes a second compression protrusion 121 protruding to the first plate-like part 101 side at a position facing the first compression protrusion 111. The first plate-like part 101 and the second plate-like part 102 include a position holding contact mechanism 113 that prevents the second plate-like part 102 from moving forward in a first state where the first plate-like part 101 and the second plate-like part 102 are in proximity. The position holding contact mechanism includes a contact object portion provided at the first plate-like part, and a contact portion provided at the second plate-like part and coming into contact with the contact object portion.SELECTED DRAWING: Figure 4【課題】圧迫凸部の位置がずれにくいチューブクランプを実現できるようにする。【解決手段】医療用チューブクランプ１００は、第１板状部１０１と第２板状部１０２とを備えている。第１板状部１０１は、第１圧迫凸部１１１とを有する。第２板状部１０２は、第１圧迫凸部１１１と対向する位置において第１板状部１０１側に突出する第２圧迫凸部１２１を有する。第１板状部１０１及び第２板状部１０２は、第１の板状部１０１と第２の板状部１０２とが近接した第１の状態において第２板状部１０２が前方に移動することを防ぐ位置保持当接機構１１３を有し、位置保持当接機構は第１板状部に設けられた被当接部と、第２板状部に設けられ、被当接部と当接する当接部とを有する。【選択図】図４
