ABSTRACT:
A coupling ring (30) including a coupling nut (40) circumposed around a plurality of serrations (18) and an unlocking sleeve (50) rotatably mounted to the coupling nut. An arcuately shaped lock member (60) carried by the coupling nut, in cooperation with a spring (66), allows rotation of the nut in a coupling direction and prevents rotation in an uncoupling direction, the lock member being pinned at one end (60a) to the coupling nut and free at the other end (60b) to pivot, the other end being provided with teeth (68) to releasably engage with succeeding of the serrations. The uncoupling sleeve (50) carries a lifter (54) having a free end (54b), the free end normally biased by a compression spring (52) into spaced-apart relation to lock member (60) and adapted to drive nut (40) in the coupling direction. Sleeve (50) with lifter (54) is mounted to rotate in the uncoupling direction independently of coupling nut (40), uncoupling rotation of uncoupling sleeve (50) forcing free end (54b) of lifter (54) against lock member (60) to deflect the pivotable end (606) upwardly and thereby disengage teeth (68) thereof from engagement with serrations (18).
