An infusion connector. By arranging a body (1) whose outer surface and outer edge are non-sharp structures and enabling an infusion puncture device (16) not to protrude out of the body (1), a nursing staff is prevented from being exposed to an infusion puncture environment having sharp objects when the nursing staff performs infusion operations. The infusion puncture device (16) has a hollow channel, the infusion puncture device (16) is provided with a connector liquid inlet (11), an connector liquid outlet (12) communicates with a liquid storage chamber of an external infusion container by means of the connector liquid inlet (11), a very small quantity of particles or chips are generated, and harm of the particles to a human body 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 cooperating with an opening in the external infusion container, the objective of rapid and convenient infusion can be achieved. 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.La présente invention concerne un raccord de perfusion. En disposant un corps (1) dont la surface externe et un bord extérieur sont des structures arrondies et en permettant à un dispositif de ponction de perfusion (16) de ne pas faire saillie hors du corps (1), un personnel soignant évite dêtre exposé à un environnement de ponction de perfusion présentant des objets pointus lorsque le personnel soignant exécute des opérations de perfusion. Le dispositif de ponction (16) présente un canal creux, le dispositif de ponction (16) est muni dune entrée de raccord de liquide (11), une sortie de rac
