A sprayhead (1) for example for an aerosol or pumpspray container (4) comprises a support (2), a fluid outlet (12) mounted on the support (2), a passageway (14) connected to the fluid outlet (12) at a first end and connectable to a fluid source at a second end, the passageway (14) being movable between a first non-operative position and a second position in which, in use, it is connected to a fluid source such that fluid can pass through the passageway to the fluid outlet, a member (3) secured relative to the support (2), the member being movable between a non-operative position and a further position in which it allows the passageway (14) to attain its second position, and a lock (28) selectively operable to lock the member in its first position, thereby preventing the member from urging the passageway to its second position unless the lock is released.
