Abstract
A medical connector for manually connecting a fluid conveying conduit that is in fluid communications with a patient's vasculature and having a junction terminal at an end thereof to a fluid conduit for administration of fluid to the patient. The connector is formed of two components. The first component includes a cannula hub to which a cannula is mounted, a base extending from the hub and fingers extending from the base. The second component is a collar including a support and bars extending therefrom. The collar is manually slidable along the first component in the direction the cannula extends between a retracted position and a locking position. The bars engage the fingers to flex into engagement with the junction terminal. The bars are elastically deformable to provide a spring force for locking the fingers on the junction terminal.
