Abstract
A coupler for an excavator has first and second recesses for receiving first and second pins, respectively, of an attachment. A latching member is movable into and out of a latching state in which it closes the second pin-receiving recess. A blocking member is movable into and out of a blocking state in which it closes the first pin-receiving recess. An actuator is provided for moving the first latching member into and out of the latching state, the actuator acting indirectly upon the blocking member to move the blocking member into and out of its blocking state as the latching member is moved into and out of its latching state. Preferably the actuator acts upon the blocking member via a resiliently deformable member acting between the actuator and the blocking member whereby the resilient member can deflect should the blocking member be obstructed to avoid excessive loading on the actuator.
