Abstract
An electronic instrument case formed of breakable plastic and having a section of reduced thickness which is firmly secured to the remainder of the wall of such enclosure by a retainer. Such reduced thickness section can be broken away from the remainder of the wall of the enclosure but it is held in attached relation thereto to thereby provide a "breathing" opening for such enclosure.
