Actuator for an inhaler for delivering medicament by inhalation, having a main body with a tubular member for receiving a canister containing medicament and having a valve stem extending therefrom; and an outlet assembly, as a part formed separately of the main body, including a mouthpiece for guiding medicament to the mouth of a user and a nozzle block for receiving the valve stem of the canister and delivering medicament from the canister into the mouthpiece. The actuator belongs to a range of inhaler actuators where the outlet assembly is a common part for the range of actuators, and the members of the range of actuators differ by the physical appearance of the main body. The outlet assembly is formed such that it has all parts of the actuator that come into contact with the medicament during normal use, and the main body and the outlet assembly are configured so as to snap-fit together and are provided with complementary snap catch members.
