Abstract
Abstract Spring clips for holding lamp shades such as but not limited to fragile globe and funnel shapes, onto lamp fixtures include elongated types clips that connect to the stem beneath the socket of the lamp fixture. The longitudinal clips springably expand within the neck and lower interior expanding portion of the globe shade, securely holding the latter in place to the lamp fixture. The spring clips have great applicability to the light fixtures on ceiling fans offering a secure fastening system that prevents accidental dislodging of the fragile shade when vibrations from the spinning fan occur. The spring clips allow the shades to be more easily put in place over the overhead type light fixtures as compared to the traditional method of using side screws to support and secure the shades. The clips can have hook or barb ends which prevent the accidental release of the shade from the fixture. A safety sleeve can be included which slips over the socket so that the sleeve and the clip together help prevent the shades from being accidentally dislodged from the socket.
