Glue to fix toboggan (4)
I believe the answer is:
luge
'toboggan' is the definition.
(I know that toboggan can be written as luge)
'glue to fix' is the wordplay.
'to fix' is an anagram indicator (I've seen 'fixed' mean this).
'glue' is an anagram of 'LUGE'.
(Other definitions for luge that I've seen before include "Winter sport" , "Small sledge for one" , "Racing sled for one or two people" , "Light toboggan" , "Glue (anag) - racing toboggan" .)
