The attachment (20) has a body (26) for engagement with the nozzle (14) so that, when the canister (10) is actuated, the body (26) moves relative to the canister body. The attachment (20) also has count means which are arranged to register actuations of the canister (10) in response to the actuation of switch means (22) by the movement of the body (26) of the attachment (20) relative to the canister body. The entire attachment (20) may be movable relative to the canister body and the switch means (22) may interact with a portion of the canister body. |
