Ive-32o fhis invention relates to aiclip for f hiio'i'escent lamp sockets adapted to retain the lamp in the socketand prevent its falling. A cornnionmeans of mounting fluorescent tubular lamps is hy means of a socket at each end depending from its support, which socket is provided with grooves opening through a lower part thereof into which the projecting pincontacts on the end of the lamp are inserted to engage proper contacts. in the socket to establish electrical connection therewith. Due to variations in the iengthof the lamp and in the mounting of the socket and other reasons,- these pins may not extend tothe full length into the socket, and for other reasons they-may} jar out so that the lamp falls, with: resultant breakage of the lamp and possible: injury to. people:
It is therefore an object ofthe present inven tion to" provide a simple and; efiective'f ciip' which may be attached; to the socket and.-arrangedrto eifectively retain thelamp-inthesocket;
It is also an: object to provide: such; a? device whichisnotbuiltinto-the socketi'asia.partrthereof; but is a separate device to be applied to the socket and, therefore; may; be applied; tos'socli ets the lamp from the socket 'orinstall'ing the lariip therein.
With the foregoing and otherobjects in' riew, I" have devised the construction illustrated in the accompanying drawing forming a part of'tliis specification. It is, however, to:'b.e'- ungerstoodthe device is notlimite'd to thes-pe'cific details of construction and arrangement shown, but may embody various changes and modifications Within the scope of the invention.
In this drawing:

but is so constructed as to be able to hold the lamp in position in the socket. In the preferred construction it comprises a curved loop or substantially U-shape extending around under the end portion of the lamp with the free ends of the sides pierced at to receive pivot lugs 23, which are notched, as shown at 26, to retain these ends of the loop on the pivots. The loop may be bent outwardly and backwardly upon itself, as shown at 21, to form a handle or grip by means of which the loop may be swung laterally out of position, as indicated by dotted lines Fig. 1, to permit insertion and removal of the lamp into or from the socket, and then swung back to the holding position.
Means is provided for retaining this loop in the lamp holding or retaining position, and in the form shown this comprises inwardly extending nubs or projections 28 pressed inwardly from the sides of the loop and adapted to engage a shoulder on the ferrule H of the lamp to retain the loop and prevent its accidentally swinging out of position. In the form shown these projections seat into the groove l2 formed in the ferrule of the lamp and cooperate with the shoulder. provided thereby to hold the loop in position. This loop may be a strip of thin metal, and as it has a certain amount of spring or resiliency it will yield to permit the projections 28 to pass over the end of the lamp into the groove and spring into the groove, so that this action will retain them in the groove and retain the loop in the lamp holding position. It will, however, permit the loop to be swung outwardly, as shown in dotted lines, Fig. l, to permit insertion of the lamp into or removal from the socket.
It will be understood from the above that the device is a very simple one, involving a minimum number of parts. It is not built into the socket as a part thereof and, therefore, does not require a rebuilding or redesigning of the socket or a change of the socket in any way, but it is mounted on the socket as a distinct and separate device, and, therefore, may be applied notonly to new sockets, but also to old sockets already installed. The mounting of this device onthe socket is a very simple operation, and it in no way interferes with quick and easy insertion or removal of the lamp when it is desired to install or renew a lamp, but effectively retains the lamp in position and prevents its accidental loosenin or jarring out in operation.
Having thus set forth the nature of my invention, what I claim is:
