A valve connector for an infusion medical line comprises a hollow tubular body 1 with an axial hollow spike 2 and an intermediate sealing member 3. The inlet end 4 of the hollow tubular body 1 is designed to engage with a fluid introducer. The axial hollow spike 2 is placed with its open end facing the outlet end 10 of the hollow tubular body and its closed end facing the inlet end 4 of the hollow tubular body. The axial hollow spike 2 also has an oval hole 31 in it close to its closed end. The intermediate sealing member 3 has an elastic head 35 with a normally closed slit 38 in it. When a fluid introducer is pushed into the hollow tubular body through the slit 38 in the elastic head 35 of the intermediate sealing member 3, the axial hollow spike 2 with the oval hole 31 in it will enter the fluid introducer. An inelastic sliding cylindrical ring 55 that surrounds part of the intermediate sealing member 3, maintains the sealing effect of the intermediate sealing member 3 around the fluid introducer.
