The device for holding a partition wall on a wall in the interior of a vehicle, particularly on a ceiling paneling of an airplane cabin, comprises a holding element (24; 24'; 24'') to be attached to the vehicle and having at least one recess (34; 34''), and a slider (36; 36'') arranged on the holding element (24; 24'; 24'') and formed with a receiving opening (38; 38'') for receiving an receivable element (26; 26'') of the partition wall (18; 18''). The slider (36; 36'') is supported on the holding element (24; 24'; 24'') for movement on a moving path between a cover position in which the slider (36; 36'') closes the recess (34; 34'') of the holding element (24; 24'; 24''), and an open position in which the receiving opening (38; 38'') is arranged within the recess (34; 34'') of the holding element (24; 24'; 24'').
