PROBLEM TO BE SOLVED: To provide a catheter connector capable of preventing a catheter from coming off.SOLUTION: A catheter connector 1000 includes: a first member 100 which has a first through-hole 112, into which a catheter 10 is inserted from one end 112a side, and in which a female screw 116 is provided to an inner surface 115 on the one end 112a side； an elastic member 300 which is housed in the first through-hole 112, and through which the catheter 10 penetrates； and a second member 200 including a screwing part 210 through which the catheter 10 penetrates, and which is provided with a male screw 214 inserted into the first through-hole 112 from the one end 112a side and screwed with the female screw 116, and a lid part 230 connected to the screwing part 210 through a rotation axis 220. The elastic member 300 is pressed by the screwing part 210 and fixes the catheter 10. In a state that the catheter 10 is fixed to the elastic member 300, the lid part 230 is folded back at the rotation axis 220 and fixed to the first member 100.SELECTED DRAWING: Figure 3【課題】カテーテルが外れることを抑制することができるカテーテルコネクタを提供する。【解決手段】本発明に係るカテーテルコネクタ１０００は、一端１１２ａ側からカテーテル１０が挿入され、一端１１２ａ側の内面１１５に雌ねじ１１６が設けられた第１貫通孔１１２を有する第１部材１００と、第１貫通孔１１２内に収容され、カテーテル１０が貫通する弾性部材３００と、カテーテル１０が貫通し、一端１１２ａ側から第１貫通孔１１２に挿入されて雌ねじ１１６と螺合する雄ねじ２１４を備えた螺合部２１０と、回動軸２２０を介して螺合部２１０に接続された蓋部２３０と、を有する第２部材２００と、を含み、弾性部材３００は、螺合部２１０に押圧されてカテーテル１０を固定し、カテーテル１０が弾性部材３００に固定された状態において、蓋部２３０は、回動軸２２０で折返されて第１部材１００に固定される。【選択図】図３
