ABSTRACT:
An eyeglass element of spectacles, to which a component, such as a nose piece or a temple piece of the spectacles or an ornamental piece, is to be affixed, includes a through hole having an enlarged end portion in which an actuating portion of a connecting member which is threadedly connected to the component is received when the connecting member assumes its tightened position. The connecting member may be configurated as a nut having a transverse slot extending across a threaded bore of the nut, and then a screwdriver having a bifurcated end portion may be used for tightening the nut and subsequently the portion of the stem onto which the nut is threaded which extends beyond the nut may be severed from the remainder of the stem. The component being affixed to the eyeglass element may be prevented from rotating during the tightening of the connecting member by being provided with a projection which is received in a non-circular recess in the eyeglass element which extends transversely from the through hole at the end which is remote from the enlarged end.
