The dispensing apparatus is used with twin cartridges that have two axially parallel storage cylinders and a nozzle piece connecting them. The apparatus has two plungers, one for each storage cylinder, guided to move longitudinally, and a holder for interchangeable cartridges which has a guide for the nozzle piece of a cartridge. To allow the use of two different types of cartridges, with cylinders of different diameter ratios, the holder is provided with a retention device designed to align the axes of the storage cylinders with those of the plungers; the retention device has separate grippers associated with each plunger, and these are dimensioned for different cylinder diameters. Different cartridges can be aligned between one of the grippers and the cylinder it grips, in conjunction with the guide for the nozzle piece, while the other gripper leaves the other cylinder free.
