Abstract
Abstract A device for connecting a printed circuit board to a mounting bar, includes a flat H-shaped leaf spring having first and second paris of flat legs integral with a flat crosspiece having a depending flat peg. One pair of legs has opposing hooks which engage under an abutment in the bar. The other pair of legs has noses with camming faces engaging in a hole in the board. The crosspiece overlays the abutment while the peg engages in a slot in the abutment which also receives the edge of the board.
