Abstract
A coupler comprising two jaws and a latch for each jaw, one of the latches being powered for movement between a latching position and a non-latching position, and being associated with a blocking mechanism that is remotely movable between a blocking position and non blocking position, and the other latch being independent of the blocking mechanism, but being also remotely moveable between a latching position and a non-latching position, wherein the powered latch, in its non-latching position, can maintain both the blocking mechanism in its non blocking position and the other latch in its non-latching position, irrespective of the orientation of the coupler.
