A quick-coupler for operably connecting a bucket or other implement to the arm or dipper-stick of an excavator, backhoe and/or other machine includes a first and second laterally spaced-apart rib assemblies. A first upper bearing plate is connected to the first rib assembly and a second upper bearing plate connected to the second rib assembly. At least one of the first and second upper bearing plates and the lower bearing plate includes a tab projecting outwardly therefrom that is inserted into a corresponding tab-opening defined in one of the first and second rib assemblies. A lock member is slidably positioned in the slot, and an actuator is located in the space between the first and second rib assemblies. The actuator is operably coupled to the lock member for moving the lock member between first and second operative positions. A method of constructing a coupler is disclosed.
