A dummy closure plug for a medical gas terminal unit, when locked in the unit prevents the connection of equipment thereto. The dummy closure plug comprises (a) a spigot 22 adapted to be locked in position by the locking mechanism of the medical gas terminal unit, the spigot 22 being of such a length that when the dummy closure plug is in a locked position in the terminal unit, the spigot does not reach the terminal unit check valve, and (b) a body 20 from which the spigot projects and which, when the closure plug is in locking engagement with the socket 6 of the terminal unit, obstructs access to the release collar 40. The body 20 has at least one aperture 30 therethrough for the insertion of an unlocking tool to urge the release collar 40 to release the dummy closure plug.
