A connector system for administration of medical fluid including, a male connection element (300, 1200) having a body that includes a distal portion (320) ending at a distal end (321) and a proximal portion (310) ending at a proximal end, a lumen (315) being defined through the body for the passage of liquid from the distal end to the proximal end, a female connecting element (10, 1010) defining a sheath (30, 1030) to receive the distal portion (320) of the male connecting element (300), a distal end (32) of the sheath (30) extends over a partition (40, 1040), in which, a central region (41, 1041) of the partition is formed from a material having a thickness substantially greater than a peripheral region (42, 1042) of the partition surrounding the central region, and the distal end of the male connecting element includes means of rupture (365, 375) of the peripheral region of the partition when the connection element m Acho (300, 1200) is received in the female connection element (10, 1010) to form a connection, and in which in addition to the breaking means (365, 375), the distal end (32) of the connection element male (300, 1200) is blunt, in order to prevent accidental connection of the male connection element with a standard IV connection hole； and wherein the male connecting element (300, 1200) is a given perforator for infusion equipment for the administration of medical fluids, and the female connecting element (10, 1010) forms an access hole to a container of medical fluidUn sistema conector para administración de fluido médico incluyendo, un elemento de conexión macho (300, 1200) que tiene un cuerpo que incluye una porción distal (320) que termina en un extremo distal (321) y una porción próxima (310) que termina en un extremo próximo, definiéndose un lumen (315) a través del cuerpo para el paso de líquido desde el extremo distal al extremo próximo, un elemento de conexión hembra (10, 1010) que define una vaina (30, 1030) para recibir la porción distal (320
