<p>A casing for electrical apparatus comprises a pair of hollow body parts (10, 11) each of which has an edge (17, 18), the edges being contiguous when the parts are assembled together. Each edge is formed with first and second portions (23, 21) which are received in a rebated recess of a tubular connector element (24). The two body parts can be flexed apart to insert contents but are prevented from separating by the edge formations, the first portions (23) resisting separation of the body parts at least when they are partly separated, whilst the second portions (21) prevent lateral removal from the recess of the tubular connector element (24). <IMAGE></p> |
