Order used to keep the hose in place (6)
I believe the answer is:
garter
'order' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for garter that I've seen before include "Band around the leg or arm" , "Band to keep a stocking or sleeve up" , "- Belt; - snake; - stitch" , "Sock supporter" , "Support for a stocking" .)
