Inside a connector body (112, 114; 300) of a medical connector providing a fluid flow conduit, a one-way valve (118) is fitted directly into one end of a stop valve (116) in a manner providing a fluid tight seal between these valves. The stop valve (116) prevents fluid flowing out of the end (111; 311) of the connector body (112, 114; 300) unless a complementary end of a separate device (not shown), typically a Luer lock connector, engages the end of the connector body and opens the stop valve (116). To facilitate manufacture and assembly, the one-way valve (118) and the stop valve (116) can be formed as parts of a single piece of elastomeric material, the parts being hingedly connected so that the one-way valve part (118) can be folded over to be fitted directly into the end of the stop valve part (116). A further possibility, also applicable when only a stop valve (116) is provided, is that the connector body (300) may be formed in one piece with a folding, snap fit closure (312).
A medical connector comprising a connector body having first and second apertures in fluid communication via a fluid flow conduit, a one-way valve disposed in the connector body to allow fluid to flow from the first aperture, through the fluid flow conduit and out of the second aperture, but not to allow fluid to flow from the second aperture and through the fluid flow conduit to the first aperture, and a stop valve which prevents fluid flowing out of the second aperture of the connector body unless a complementary end of a separate device engages the second aperture and opens the stop valve,
