Pane holder (4)
I believe the answer is:
sash
'pane holder' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sash that I've seen before include "Band worn over shoulder or round waist" , "Brown bread for waist or shoulder" , "Ribbon worn over the shoulder" , "type of cord?" , "Strip of cloth - type of window" .)
