A device for blowing gas into a metallurgical vessel contains at least one gas flow channel fluidly connecting a gas inlet located at one end to a gas outlet located at the opposite end. The channel is in the shape of a slit. The gas channel contains a series of continuous concave bridges connecting the opposing surfaces defining the channel, with their concave side oriented towards the gas outlet. The concave bridges are disposed in a staggered arrangement, such that any shortest line running from the gas outlet to the gas inlet of the channel necessarily intercepts the concave side of at least one bridge. The device is resistant to clogging by infiltrated molten metal or slag.
