A connector coupling that comprises a connector body, a first collar that receives the connector body, and second collar that surrounds the first collar. A movable ratchet ring is supported by the connector body and includes at least one locking member. The movable ratchet ring is axially movable with respect to the first collar between engaged and disengaged positions. A stationary ratchet ring is coupled to the first collar and includes at least one locking member. When the movable ratchet ring is in the engaged position, the locking members of the rings are engaged, and rotating the second collar from the first position to the second position with respect to the first collar moves the movable ratchet ring to the disengaged position away from the stationary ratchet ring such that the locking members are disengaged, thereby allowing rotation of the first collar with respect to the connector body.

A connector coupling according to claim 1, wherein said movable ratchet ring and said stationary ratchet ring include a plurality of locking members. 3. A connector coupling according to claim 2, wherein said locking members of said movable and stationary ratchet rings are axially extending interengaging teeth. 4. A connector coupling according to claim 1, further including a biasing member supported by said connector body adjacent said movable ratchet ring and remote from said stationary ratchet ring, said biasing member biasing said movable ratchet ring in said engaged position. 5. A connector coupling according to claim 1, wherein said movable ratchet ring is located inside said first collar near said second end thereof; andinternal threads are disposed near said first end of said first collar. 6. A connector coupling according to claim 1, wherein said second collar includes a disengaging flange that contacts and pushes said movable ratchet ring to said disengaged position when said second collar is rotated from said first to said second position. 7. A connector coupling according to claim 6, wherein said disengaging flange extends radially inwardly from an end of said second collar, thereby defining an opening that is smaller than an opening at an opposite end of said second collar. 8. A connector coupling according to claim 6, wherein said disengaging flange includes a radially extending portion and an axially extending portion such that said disengaging flange is substantially L-shaped in cross-section. 9. A connector coupling according to claim 6, wherein said radially extending portion and said axially extending portion of said disengaging flange define a receiving area therebetween; andsaid receiving area is adapted to receive substantially an entirety of said stationary ratchet ring when said second collar is in said second position with respect to said first collar. 10. A connector coupling according to claim 6, wherein said disengaging flange extends substantially continuously around a circumference of an end of said second collar. 11. A connector coupling according to claim 1, wherein said first collar includes at least one outer engagement member adapted to engage a corresponding inner engagement member of said second collar such that said inner and outer engagement members are disengaged when said second collar is in said first position and said inner and outer engagement members are engaged when said second collar is in said second position. 12. A connector coupling according to claim 11, wherein said outer engagement member is a bayonet channel and said inner engagement member is a detent. 13. 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; anda 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. 14. A connector coupling according to claim 13, wherein said disengaging member is an annular flange extending radially inwardly from an end of said second collar. 15. A connector coupling according to claim 14, wherein said flange includes a radially extending portion and an axially extending portion such that said flange is substantially L-shaped in cross-section, said receiving area is defined between said radially and axially extending portions. 16. A connector coupling according to claim 13, wherein said movable ratchet ring and said stationary ratchet ring include a plurality of locking members. 17.
