Anti-vibration connector coupling with disengagement feature

A connector coupling, comprising:

• a connector body;
• a first collar having opposite first and second ends, said first collar receiving said connector body;
• a second collar surrounding said first collar, said second collar being rotatable with respect to said first collar between first and second positions, said second collar including a disengaging member at an end thereof, said disengaging member defining a receiving area;
• a movable ratchet ring supported by said connector body;
• said movable ratchet ring including at least one locking member, said movable ratchet ring being axially movable with respect to said first collar between engaged and disengaged positions, said movable ratchet ring being in contact with said disengaging member of said second collar when in said disengaged position;
• and
• a stationary ratchet ring coupled to said first collar, said stationary ratchet ring including at least one locking member corresponding to said at least one locking member of said movable ratchet ring, said stationary ratchet ring being received in said receiving area of said second collar when said second collar is in said second position,
• wherein rotating said second collar from said first position to said second position with respect to said first collar moves said movable ratchet ring to said disengaged position via said disengaging member of said second collar pushing said movable ratchet ring away from said stationary ratchet ring such that said locking members are disengaged, thereby allowing rotation of said first collar with respect to said connector body.
