A protective casing (1) for optical instruments, particularly for video cameras, having a tubular casing shell (2) with a sealed front wall (3) added to the respective end, a backwall (4), an instrument support (11) placed within the casing shell and rigidly connected to the backwall, and a casing support (9) placed outside the casing shell for the attachment of the protective casing (1) on a stationary support (12). The electrical connections pass through the backwall (4), and the casing shell can be removed from the backwall of the instrument support (11). In order to facilitate the assembly, the instrument support (11) has a U-shaped section forming a trough open on the top with two parallel side walls and a crossbar connecting both sidewalls, and the inner side of the side walls are equipped with several grooves located parallel to the casing axis in order to allow the insertion of at least one instrument support plate at adjustable heights.
