A connector that has a coupling nut (14) that is rotatable about a barrel (12), with an annular space (42) between them, and with a resistance ring (40) lying in the annular space. The resistance ring allows the nut to rotate with moderate friction in a mating direction M, and provides higher resistance to nut rotation in an unmating direction U. The resistance ring is formed from a metal band with primarily straight band sections (60, 62, 64, 66) that alternately extend at inward and outward inclines from the circumference direction C. As a result, the resistance ring zig-zags by alternately engaging the nut surface (52) that faces the annular space, then the barrel surface (50) that faces the annular space, etc. Some of the radially outer ends of the straight sections are bent into small half circles (67) that fit into corresponding slots (68) in the nut to fix the resistance ring relative to the nut. The radially inner ends of the straight sections form bumps (70) that ride over saw teeth (74, 76) formed on the barrel surface.
