Slaps on the wrist (5)
I believe the answer is:
cuffs
This clue is a double definition.
'slaps' is the first definition.
(cuffing is a kind of slapping)
'on the wrist' is the second definition.
(a shirt cuff covers the wrist)
(Other definitions for cuffs that I've seen before include "They may have links" , "Sleeve-ends" , "Sleeve ends" , "Arresting items" , "Clips around the ear" .)
