Abstract
A device for fitting a handling block to an eyeglass lens to which the handling block adheres temporarily includes a receptacle into which the handling block is push-fitted. An ejector system associated with the receptacle facilitates disengagement of the handling block from the receptacle after it is fitted to the lens. This system is operative outside the receptacle and engages operatively on the eyeglass lens concerned. It comprises two ejector fingers movable parallel to the axis of the receptacle against return springs.
