A medical connector, usable to securely couple a first tubular medical device to a second tubular medical device, includes first and second fittings cooperating with the first and second medical devices, respectively. The first and second fittings may each include a nipple, a ferrule, or some other structure that is connected to the associated medical device and that is connectable to the other fitting. The second fitting may additionally include a tubular sleeve that slides over the second medical device and the ferrule or other component of the second fitting. The two components of the second fitting are sequentially connectable to the first fitting through distinctly different motions to provide a redundant, secure connection. For example, the first fitting may include a first set of left-handed threads and a second set of right-handed threads, and the components of the second fitting may have corresponding left-handed and right-handed threads.
