Abstract
An elbow coupler includes a linkage for locking the coupler to an adapter. The linkage has a resilient, laterally deflectable link that limits the forces applied to the linkage thereby preventing the components of the linkage from being overstressed. A spring loaded, blocking sleeve prevents the coupler from normally remaining upright on an adapter, unless it is locked thereon through use of the locking linkage. A flapper valve is interconnected with the blocking sleeve to the end that the valve is normally closed and then opened when the coupler is locked onto an adapter.
