The invention relates to slats ( 1 ) for a venetian blind comprising slats of very large dimensions, both relating to the width of the slats and to the longitudinal extension of the slats ( 1 ). Thus the venetian blind comprising these slats can be made to cover very large window openings or other parts of buildings and rooms. The slats ( 1 ) are provided with longitudinal edge portions ( 3 ) serving the dual purpose of increasing the overall rigidity of the slats ( 1 ) and of providing attachment means ( 12 ) for support cords of the slats ( 1 ). The slats are operated by pairs (typically two) of lift and tilt cords running in parallel along the longitudinal edges of the slats ( 1 ), thereby avoiding passages through the slats ( 1 ), which is advantageous both from an aestetical point of view and from the point of view of the necessary production technique for the slats ( 1 ). The invention also relates to releasable attachment means ( 12 ) for connection the slats ( 1 ) to the tilt cords of the venetian blind. The Invention furthermore relates to the venetian blind as such comprising the above slats ( 1 ) and attachment means ( 12 ), and due to these is becomes possible to assemble the complete venetian blind in situ in a very easy manner. Also the removal and replacement of individual slats ( 1 ) without the necessity to dismantle major portions of the venetian blind is greatly facilitated according to the invention. Finally the invention also relates to a lift- and tilt mechanism for controlling tilting and raising/lowering of the slats ( 1 ).
