A device and method for retaining pigment-conducting tubes in a paint mixing machine includes a nozzle having an array of holes to accommodate the pigment-conducting tubes and a pair of lock plates, attachable to the nozzle and each having a like array of apertures, as well as offset screw holes. When the lock plates are attached to the nozzle and the screw holes are aligned, the apertures are offset, causing deformation of the pigment-conducting tubes, which deformation serves to retain the pigment tubes in the nozzle. A paint mixing machine having pigment reservoirs and valves for controlling pigment flow also has a movable mounting plate, upon which the nozzle is mounted, and the nozzle is thereby movable under microprocessor control between a dormant position and a dispensing position, which, in combination with a sight, allows more precise alignment of a paint can under the nozzle dispensing location.
