A device for protecting a circuit board assembly, having insertion type edge connectors, disposed along at least one side edge thereof, from damage due to electrostatic discharge through the circuits of said assembly, said device comprising in combination: an elongate clamping member of resilient material having a longitudinal mouth co-extending therewith; an electrically conductive foam material disposed within said mouth along at least one edge thereof and co-extending therewith to present an opening of predetermined width; said device being clipped onto said one edge of said circuit assembly, which has a thickness that exceeds said predetermined width of said opening, in such alignment as to present the connectors disposed along said at least one side in frictional contact with said foam material whereby said device clampingly engages said circuit assembly and effects electrical connection between and among said edge connectors and said foam material to allow electrostatic discharge to proceed through said foam material.
