A coupler for an excavator, the coupler comprising a body having first and second recesses for receiving first and second pins, respectively, of an attachment; a latching member movable into and out of a latching state in which it at least partially closes said second pin-receiving recess; and a blocking member movable into and out of a blocking state in which a portion of the blocking member at least partially closes said first recess, actuating means for moving said first latching member into and out of said latching state, said actuating means acting indirectly upon said blocking member to move said blocking member into and out of its blocking state as the latching member is moved into and out of its latching state. Preferably the actuating means acts upon said blocking member via a resiliently deformable member acting between the actuating means and the blocking member whereby said resilient member can deflect should the blocking member be obstructed to avoid excessive loading on the actuating means.
