An infusion connector. By arranging a body (1) whose outer surface and outer edge are non-sharp structures and arranging a separator (123), a nursing staff is prevented from being exposed to a puncture environment having sharp objects when the nursing staff performs infusion operations. By bluntly destroying pseudo soldering connections among sealing films by using the separator (123), a liquid storage chamber of an external infusion container can be opened, a very small quantity of particles or chips are generated, and harm to a human body due to entry of the particles or the chips to the infusion container and mixture of the particles or the chip with a liquid medicine is reduced. By arranging threads, a fastening structure and other forms of fixing devices (2), the infusion connector is fixedly connected to the external infusion container, and more infusion accessory assemblies can be carried, so that a nursing staff can select more infusion accessory assemblies that are more suitable for satisfying demands in disease condition. By arranging a blocking device (15), the germ-free condition in an infusion tube is maintained, and higher infusion safety guarantee can be provided to a patient.Linvention concerne un raccord de perfusion. En disposant un corps (1) dont une surface externe et un bord externe ne sont pas des structures tranchantes, et en disposant un séparateur (123), un personnel soignant ne peut pas être exposé à un environnement de perforation ayant des objets tranchants lorsque le personnel soignant exécute des opérations de perfusion. Par destruction brutale de pseudo-raccordements de soudage parmi des films détanchéité à laide du séparateur (123), une chambre de stockage de liquide dun récipient de perfusion externe peut être ouverte, une très petite quantité de particules ou plaquettes est générée, et un risque pour un corps humain en raison de lentrée des particules ou plaquettes dans le récipient de perfusion et dun mélange des particules ou plaq
