Speedy Frenchman pulled up zip (8)
I believe the answer is:
fastener
'zip' is the definition.
(I've seen this before)
'speedy frenchman pulled up' is the wordplay.
'speedy' becomes 'fast' (similar in meaning).
'frenchman' becomes 'rene' (common French name).
'pulled up' says the letters should be written in reverse.
'rene' backwards is 'ener'.
'fast'+'ener'='FASTENER'
(Other definitions for fastener that I've seen before include "Clip, catch, etc" , "Clip, catch or other means of fixing securely" , "Stud perhaps" , "Device that closes clothes - may be a zip" , "Fixer, securer" .)
