An electrically conductive box for enclosing a high frequency electronic circuit has one open side and is divided into a number of chambers by partitions. The edges of the open end of the box and the partitions are formed with tabs. A resilient conductive sheet covers the open side of the box and is formed with holes through which the tabs extend. An electrically conductive plate is also formed with holes through which the tabs extend and is placed on top of the sheet. The tabs are twisted to clamp the plate and sheet to the box. The inner surface of the plate is formed with protuberances to resiliently deform the sheet so that the sheet is stretched for firm mechanical and electrical contact with the edges of the box and partitions.
