A dispensing device (1), for example for dental impression material, comprises a chamber (2, 3) for containing material to be dispensed. The chamber has a dispensing outlet (6) which is so configured that a removable nozzle (7) can be secured thereto to dispense material from the chamber. A locking member (8) is pivotally-movable relative to the chamber into an engaged position (FIG. 2) in which the nozzle is secured to the dispensing outlet by the locking member and the locking member is retained in the engaged position by the nozzle.
