A jumper strip for terminal blocks or the like comprises in one embodiment a pair of fastener engaging portions coupled together by a resiliently deflectable upstanding arched portion so that the spacing between the apertures may be selectively varied by exerting suitable pressure on the arched portion. The strip may be disposed over terminal screws having a center to center spacing slightly greater or smaller than the spacing between the apertures in the strip whereby upon release of the arched portion the strip is urged against the shank of the terminal screws and retained in position during the loosening and tightening of the screws. In another embodiment, a plurality of such fastener engaging portions are resiliently joined one to another in strip fashion to provide a multiple terminal shorting bar or jumper strip. The apertures are joined to a common edge of the jumper strip by a slot which may be aligned with or offset from the axis of the aperture.
