Maclean's turn to show restraint (8)

I believe the answer is:

manacles

I'm a little stuck... Click here to teach me more about this clue!

'to show restraint' is the definition.
I can't tell whether this defines the answer.

'maclean's turn' is the wordplay.
'turn' indicates an anagram.
'macleans' with letters rearranged gives 'MANACLES'.

Can you help me to learn more?

(Other definitions for manacles that I've seen before include "Shackles for the wrist" , "chains" , "Fetters for the hands" , "Handcuffs" .)

I've seen this clue in The Globe and Mail.
