A shield is provided for placing around an edge connector that is mounted near the edge of a circuit board, which can be readily mounted on the board. The shield (36, FIG. 2) includes an arm (72) with an outer part (74) that extends down along the outer board edge (70), and an arm inner part (76) that extends inwardly below the board lower surface (46) and that has a clamp end (80) that presses up against the board to thereby clamp the shield to the board without the need to drill holes or the like in the board. The board has a grounded conductive trace (50) on its upper surface, and the shield is formed of sheet metal with tabs (52, 54, 56) at its lower ends which extend horizontally and slightly below the rest of the shield sides, to press directly against the grounded trace on the board. The arm which has an inner part below the board, can include a 90.degree. bend (140, FIG. 5) so that the sheet metal inner arm part (142) lies primarily in a horizontal plane. With the connector contacts having tails with inclined portions (161-164, FIG. 6), the back side of the shield can have an inclined portion (172) at the same angle (A) as the inclined portions of the contact tails (154).
