1. A locking nipple fitting assembly for selective removable coupling with a housing having a mounting location for receiving the nipple fitting assembly, the assembly comprising:
a base having first engagement structure configured to engage structure adjacent the mounting location such that the base is secured against rotation relative to the housing;
a nipple fitting received on the base and having first and second oppositely disposed coupling features, the first coupling feature configured to mate with a complementary coupling feature of the housing at the mounting location whereby the nipple fitting may be secured to the housing; and
locking structure between the base and the nipple fitting, the locking structure configured to resist relative rotation between the base and the nipple fitting until a torque applied to rotate the nipple fitting in a loosening direction exceeds a predefined threshold.
