The female member consists of a pair of upper hooks and lower protruding eyes engageable by the male member having a pair of upper bridge pins and lower, channeled slots. Upper engagement is made between bridge pins and hooks and lower engagement by insertion of the protruding eyes into the slotted channels. Coupling is secured or released by extension or retraction of hydraulically or manually actuated pins through the slotted holes and protruding eyes.
