Toothpaste holders (5)
I believe the answer is:
tubes
'toothpaste holders' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tubes that I've seen before include "Piping" , "Long hollow conduits" , "Hollow cylindrical shapes" , "Long hollow cylinders" , "Hoses, pipes, lines etc" .)
