ABSTRACT:
A coupling apparatus having coupling body with a mechanical latch assembly. The mechanical latch assembly includes a modified latch plate. The latch plate defines a main portion having a top end and a bottom end and includes an annular aperture disposed between the top and bottom ends. A lever portion is disposed proximate the top end. The lever portion enables the latch plate to move within a coupling body, so as to operate the mechanical latch assembly in a released position and a latched position. A raised edge is disposed about a portion of the annular aperture. The raised edge is disposed proximate the bottom end and extends radially inward of the inner edge defined by the annular aperture. A pin opening is disposed proximate the bottom end opposite of the lever portion. The pin opening is positioned radially outward from the annular aperture, and defines a separate enclosed edge.
