A self-sealing male connector (20) includes a tubular male body (30) and an elastomeric resilient tip (38) disposed on the distal end (50) of the tubular male body. The elastomeric tip has a transverse size (44) that is greater that the size of a female connector (24) and a shape that differs from the female shape so that engagement of the two will result in reshaping the male tip to the shape of the female flow channel and the male will create a seal with the channel. The male tip is formed with a slit (40) and a hollow core (56) that provides a flow passage formed in the male body. As the male tip is reshaped due to engagement with a female connector, the slit opens to establish fluid flow through the male connector. In one embodiment, the transverse shape of the male tip is elliptical having a major axis (46) along which the slit is formed. In one embodiment, the male tip is oversized in all transverse dimensions and forms an edge seal with the female connector at first contact. The proximal end (52) of the male connector may be configured as a conventional female connector, a blood collection device (not shown), or other. The male body can have a Luer shape.
