Syringes found in soft sloppy nappies (8)
I believe the answer is:
panpipes
'syringes' is the definition.
('panpipe' can be a synonym of 'syrinx')
'soft sloppy nappies' is the wordplay.
'soft' becomes 'p' (musical abbreviation for 'piano').
'sloppy' is an anagram indicator.
'nappies' with letters rearranged gives 'anpipes'.
'p'+'anpipes'='PANPIPES'
'found in' is the link.
(Other definitions for panpipes that I've seen before include "Primitive wind instrument" , "Musical instrument made of reeds of different lengths" , "Simple wind instrument" , "Folk instrument" , "Crude wind instrument" .)
