A coupler is provided for implementation with front end loaders. A male face plate is connected to the arms of the front end loader, having spring biased and hydraulically released cams on the back surface thereof and maintained in juxtaposition to an aperture passing through the base plate. A female coupler portion is attached to an appropriate implement. The female coupler portion includes a pair of ribs having hooks at the top thereof for engaging the bridge pins of the male portion, and legs having cam pins extending from bottom portions of the ribs. The legs and cam pins pass through the aperture of the faced plate to make locking engagement with the cams.
