Abstract

Toggle securing device for toggle joints of conveyor pans for chain conveyors, guide pans of winning machinery guides and the like with a securing plate which secures the toggle in its receiving pocket, laterally overlaps it at the end, can be introduced from the side into a respective insertion pocket by its two ends and can be caught in one of the two superimposed insertion pockets by a plastic pin which passes through a receiving hole in one end region of the securing plate and penetrates a locking orifice in the associated insertion pocket. In order to provide a securing plate for toggle joints, which can be used for toggle joints of known designs, either using a fixing sleeve or using a plastic pin as a securing element, the securing plate has a drive-in hole for a fixing sleeve at its other end region and is designed in such a way that it can be caught on the locking orifice of the insertion pocket either by means of the plastic pin or by means of the fixing sleeve after being rotated through 180.degree..
