Abstract

A connecting system is provided with a connector adapted to be mounted to the end of a conduit for removably engaging a blunt cannula to establish fluid communication between the conduit and cannula. The connector has a housing which defines a passage for communicating with the conduit and which defines an opening to the passage. The housing also defines a generally frustoconical seating surface which decreases in diameter in the direction toward the opening. A generally fluid-impervious, resilient seal is retained within the housing passage against the seating surface. The seal defines a slit which can accommodate penetration by the blunt cannula and which can reseal upon withdrawal of the blunt cannula.
