A retainer for an adjustment device for an over-centre fastener for securing and clamping two parts ( 11, 12 ) together by applying a pulling force between said parts by means of a lever ( 14 ). The adjustment device includes an externally threaded member ( 17 a) and an internally threaded member ( 19 ) rotatable relative to one another. The internally threaded member has a friction increasing insert ( 24 ) preventing unintentional relative rotation between the externally threaded member and the internally threaded member.
