The tube () is made of a thermochromic material that reversibly changes colour at a pre-set temperature threshold, by virtue of which colour change the tube () has a first visual appearance if the temperature thereof is below the preset threshold and a second visual appearance that is different from the first visual appearance if the temperature thereof is above the preset threshold.
