Shielding enclosure for electronic components

A shielding enclosure for electronic components, comprising a hollow body, said hollow body having a sheet metal wall portion and an opening closed by a readily-removable sheet metal panel, with interdigitation between an edge zone of said wall portion and an adjacent edge zone of said panel, said interdigitation constituting a U-section channel on one of said wall portion and said panel and an interdigitating edge on the other of said wall portion and said panel, said U-section channel being integral with said one of said wall portion and said panel, said interdigitating edge being in the form of a flange and the arrangement being such that, when said panel is opened, relative movement between said interdigitating edge and said U-section channel is thereby produced.
