The retainer, which is integrally formed from a single piece of metal, comprises an anchoring portion which is retained inside a bolt hole of the of the adaptor and a tail portion which extends between the anchoring portion and an aperture in the stem of the earthworking tool. The tail of the retainer has an upturned end which catches in the aperture in the stem of the earthworking tool when the stem is wedged over the adaptor in its normal working position, thereby preventing accidental dislodgement of the earthworking tool during use.
