Abstract: A hitch for mounting a bucket on an excavator jib comprises a body (12) for mounting on a jib and defining first and second recesses (20, 21) for receiving respective first and second bucket mounting pins. A closure member (24) is mounted on the body and is movable between a retracted position, allowing location of a second bucket mounting pin in the second recess, and an extended position in which the member retains the second pin in the recess. The closure member has an axially movable carriage (26), the carriage being mounted on one or more guides extending transversely of the second recess (21).
