Positive locking connector coupling

A coupling, comprising:

• a connector body;
• an interface coupling rotatable with respect to said connector body and having an interface portion at an inner surface thereof adapted to engage a mating connector;
• an inner collar coupled to said interface coupling and surrounding said connector body, said inner collar having a main body, said main body having at least one inner retaining member including a first set of teeth and at least one first engagement member at an outer surface thereof;
• an outer collar surrounding a portion of said inner collar and having at least one second engagement member configured to engage said first engagement member of said inner collar, said outer collar being movable axially with respect to said connector body between a disengaged position when said first and second engagement members are disengaged and an engaged position when said first and second engagement members are engaged;
• a ratchet ring received inside of said inner collar and surrounding said connector body, said ratchet ring having a second set of teeth configured to engage said first set of teeth of said inner collar, said ratchet ring being axially moveable with respect to said connector body between a locked position when said first and second sets of teeth are engaged and an unlocked position when said first and second sets of teeth are spaced from one another;
• an actuating ring received in said outer collar and surrounding said inner collar, said actuating ring moving said ratchet ring from said locked position to said unlocked position when said outer collar moves from said disengaged position to said engaged position:
• and
• a biasing member supported by said connector body adjacent said ratchet ring, said biasing member biasing said ratchet ring in said locked position,
• wherein when said ratchet ring is in said locked position, said first and second sets of teeth form a ratchet that allows said interface coupling to rotate with respect to said connector body in a mating direction and prevents said interface coupling from rotating with respect to said connector body in a release direction opposite said mating direction.
