ABSTRACT WIRE GUARD DEVICE FOR WELLS A one-piece wire guard device formed of non-metallic material for use in wells includes an inner ring having a split therein defining an opening and having a portion of reduced thickness defining a hinge. Arucate sections are disposed concentrically outwardly of the inner ring and are connected to the latter by ribs. The ribs, arcuate sections and inner ring cooperate with each other to define openings for accommodating electrical wires, ropes and the like therethrough. A guard device may be flexed about its hinge from a normally closed condition to an open position to permit a drop pipe to be inserted through the opening defined by the split. Releasably locking means lock the guard device upon the drop pipe. Spacer tabs ex- tend outwardly from the arcuate sections and engage a well casing to space the drop pipe from the casing and thereby prevent damage to the drop pipe, electrical wires, safety ropes and the like extending through the guard device.
