Printed circuit board retainers are disclosed which are positioned around a board and are latched from open to closed by snap action over the borders of the board to retain the board against shock and vibration. When open, the retainers are clear of the board which allows the board to be positioned and removed both vertically and horizontally. In the first design, a pivoted arm is mounted in a housing and, when closed, the arm exerts pressure on the board which is maintained by a ridge on the arm snapping over a wall on the housing. In the second design, a latch member slides linearly through a housing to exert pressure on the board and is retained by a projection on the member snapping behind a wall on the housing. Fig. 1 illustrates the first design with rotary arm movement between open and closed positions.
