CAM-LOCK ACTUATING DEVICE FOR USE IN A LOCKING COUPLING ASSEMBLY THAT COUPLES TWO TUBULAR MEMBERS A cam-lock actuating device for use in a locking 5 coupling assembly that couples two tubular members, includes an actuatable lever (20) having a head (21) pivotally mounted on a female tubular coupler (100), an angularly positioning member (51) coupled to be turned with the head (21) , and leading and trailing releasably 10 retaining members (55, 56) independently disposed on atleastoneofthehead (21) andtheangularlypositioning member (51) such that, during turning of the actuatable lever (20) to an unlocked position, the trailing releasablyretainingmember (56) can be held in partially 15 lockingengagementwithamale tubularcoupler toprevent complete removal of the male tubular coupler from the female tubular coupler (100) while permitting gradual relief of internal pressure.
