Garden equipment, embracing special garden equipment (5)
I believe the answer is:
hoses
'garden equipment' is the definition.
(I've seen this in another clue)
'garden equipment embracing special' is the wordplay.
'garden equipment' becomes 'hoes' (I've seen this in another clue).
'embracing' means one lot of letters goes inside another.
'special' becomes 'S' (common abbreviation as in Special Air Service).
'hoes' going around 's' is 'HOSES'.
(Other definitions for hoses that I've seen before include "Flexible pipes for conveying liquids" , "Lengths of piping" .)
