Abstract
Abstract A printed circuit board in a television set casing is repaired without the connectors of this board getting shifted with respect to the holes of the rear cover, and without this board being damaged when the television set undergoes shocks or falls. The board is placed in a U-shaped strap, the arms of which are clipped on to the cover with the strap having L-shaped lugs which are simply pushed into holes of the casing, thus forming a hinged link between the board and the casing.
