Abstract
A coupler for an excavator, the coupler comprising first and second recesses for receiving the pins of an attachment, a latching hook movable into and out of a latching state in which it closes the second pin-receiving recess, and a blocking bar movable into and out of a blocking state in which a portion of the blocking bar closes the first recess. The arrangement is such that, when the blocking bar is engaged in use by an attachment pin contained within the first recess, the action of the pin on the blocking bar urges the blocking bar into its blocking state. The blocking bar is further arranged so that, in the blocking state, it lies in the path of the latching hook and that, upon movement of the latching hook out of the latching state, the latching hook engages with the blocking bar to retain it in the blocking state.
