1. A medical connector comprising:
a fluid inlet port configured for removable engagement with a connection port of a multi-use disposable set (MUDS) to establish a fluid connection beteen the fluid inlet port and the connection port of the MUDS;
a locking mechanism for reversibly locking the medical connector with the connection port, the locking mechanism having a flexible tab that is deflectable between an engaged position and a disengaged position by deflecting at least a portion of the flexible tab;
at least one sensing element in the form of at least one sensing fin extending vertically from an upper surface of the flexible tab of the locking mechanism, wherein at least one side of the at least one sensing fin has one or more reflective surfaces for reflecting visible or infrared light, wherein the one or more reflective surfaces of the at least one sensing fin are configured to interact with at least one sensor on a fluid injector system when the locking mechanism is locked in the engaged position the medical connector is securely connected to the connection port of the MUDS, and the fluid inlet port is in fluid communication with the connection port;
a patient fluid line connected, at a first end, to the fluid inlet port and having a fluid line connector at a second end configured for connection to a patient catheter to establish a fluid connection between the connection port and the patient catheter,
a one-way valve configured for maintaining unidirectional flow through the fluid inlet port into the patient fluid line,
wherein the at least one sensing element is configured to indicate that the medical connector has been inserted or installed in the connection port when the at least one sensing element is detected by the at least one sensor.
