Abstract

A housing for an electrical circuit is to be releasably mounted in an explosion-proof box without modifying the structure of the box. The housing is provided with at least one spring which extends away from the housing into engagement with an inner surface of the box. This engagement between the spring and the inner surface of the box deflects the spring, exerting force on the housing in such a way as to resiliently hold the housing inside the box.
