A latch release member extends into the latch body to retract the latches. A fitting is mounted by the latch body. A locking ring axially movable on the fitting a limited amount is spring urged to engage a slotted flange of the drill stem to transmit a turning force from the drill stem to the fitting when the head assembly is in a latched seated position.
