    摘要: The present invention relates to hooks and eyes of the type which may be screwed on to the ends of helically wound curtain cords or into supporting surfaces. In accordance with the main feature of the invention there is provided such a hook or eye of which at least a straight shank portion is at least partly surrounded over at least part of its length by a shroud that is spaced from the said shank thereby to provide an annular gap therebetween. The shroud serves either to permit the leading end of a curtain cord to extend sealingly between the shroud and the shank or to space the hook or eye from a supporting surface into which it is screwed. The shank may be screw threaded or may be unthreaded and formed of material that will become self-threaded as screwed into a thread such as that of a helically wound curtain cord. In one embodiment of the invention the shroud is moulded as an integral part of the hook or eye thereby to form therewith a one-piece unit.
