Hose holder, or a kind of snake
I believe the answer is:
garter
I believe this clue is a double definition.
'hose holder' is the first definition.
(I've seen this in another clue)
'a kind of snake' is the second definition.
(I've seen this in another clue)
(Other definitions for garter that I've seen before include "Support for a stocking" , "Sock supporter" , "- Belt; - snake; - stitch" , "Band holding up sock" , "Band to hold up a stocking" .)
