Abstract
A device for locking an optically transparent trough of an extended-field light to a housing includes a slider element, which can be actuated manually from the ouside and which is longitudinally displaceably guided in the housing, for actuating connecting elements connecting the trough to the housing. At least one respective inwardly projecting projection is disposed at edges of the trough and the housing which are adjacent and one above the other. The projections are disposed and oriented in the same direction and parallel to one another, so that they are situated one above the other in the assembled condition of trough and housing. A grip is coupled with the slider element for each pair of projections. The jaws of the grip receive the pair of projections between them, as soon as the slider element is displaced from the releasing position into the locking position.
