An adapter connector includes a housing shroud that is fitted at one end with a core and at its other end with an inner shroud. A catch hub is provided within the housing shroud for non-removably maintaining the core to the housing shroud. The core is rotatable relative to the housing shroud. The inner shroud has a catch mechanism that enables it to mate readily with a connector, if the connector is rotated in one direction. The catch mechanism is further configured to allow the connector to be removed if it were to be turned in a counter rotational direction. The connecting portion of the inner shroud is configured to accept a complementary connector. The connecting portion of the core likewise is configured to accept a complementary connector of the medication providing device.
