A connecting device which will provide a sterile connection between a container for sterile solutions and tubing for delivery of the fluid. A piercing pin is provided having a pointed end with a pin sheath surrounding the pointed end and in contact with it. The sheath surrounds the hub member of the pin and upon contact with a pierceable diaphragm, the sheath breaks away from the pointed end of the pin allowing it to become exposed with the sheath then surrounding in a uniform manner the hub member of the pin. To facilitate the uniform movement of the sheath around the hub, a shoulder section is provided in the sheath for contact with an accommodating shoulder portion of the container closure having the diaphragm. In a preferred manner, two pierceable diaphragms are provided in the closure system on the container. The first provides the initial contact and the breaking of the sheath away from the piercing pin; the second provides sterile contact between the now exposed point of the piercing pin for sterile penetration into the container.
