A retainer for an adjustment device for an over-center fastener for securing and clamping two parts (11, 12) together by applying a pulling force between the parts by 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.

The invention claimed is: 1. A retainer for an adjustment device for an over-center fastener for securing and clamping two parts together by applying a pulling force between said two parts by a lever, said adjustment device comprising: an externally threaded member and an internally threaded member rotatable relative to one another, said internally threaded member being a lock nut having a friction increasing insert and being unrotationally held by a structure movable with the lever, wherein said structure is a bent sheet metal structure having a generally inverted U-shaped portion including opposed flange portions and a web portion the flange portions being linked to a respective flange portion of the lever and the web portion carrying an integral extension, a first portion of said extension being bent at substantially 90° so as to extend along and abut a respective forwardly directed edge of the flange portions, a second portion of said extension being bent at 90° in relation to the first portion, and a third portion of said extension being further bent at 90° in relation to the second portion; flap portions originally extending in opposite directions from the third portion being bent towards the first portion so as to be mutually parallel, thus forming a nut retaining pocket. 2. The retainer according to claim 1, wherein a distance between the flap portions is slightly greater than a width between opposed surfaces of the lock nut received within the pocket so as to unrotationally keep the nut therein. 3. The retainer according to claim 1, further comprising: holes for the threaded member provided in the third and first portions the extension. 4. The retainer according to claim 2, further comprising: holes for the threaded member provided in the third and first portions of the extension.
