Abstract In a casing for accommodating electronic components mounted on a printed circuit board, a lower box has a substantially U-shaped cross section, and includes a floor and at least two side walls. Each of the side walls has a horizontal slot proximate an upper edge thereof. At least one of the side walls has a resilient snap nose formed therein which is biased inwardly in the casing. A lid is also provided for closing the lower box, and the lid may have a closing edge thereon formed as a cross-sectionally double obtuse-angled stop tongue. A bead may be provided on a lower portion of the snap nose to orient a pc board in the casing.
