Defensive spray used in spiky club (4)

I believe the answer is:

mace

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

This might be a double definition.

'defensive spray' is the first definition.
(I've seen this in another clue)

'spiky club' is the second definition.
'mace' can be an answer for 'club' (I've seen this before). I'm not sure about the 'spiky' bit.

'used in' acts as a link.

Can you help me to learn more?

(Other definitions for mace that I've seen before include "One of 9 [CLUBS]" , "Came to get ceremonial staff" , "Spiked club" , "Staff - ground nutmeg" , "Tear gas - spice" .)

I've seen this clue in The Sun.
