Musical security device protecting the locks? (7)
I believe the answer is:
hairpin
'locks?' is the definition.
Although both the answer and definition are nouns, they are not in the same form of the noun. However, I know that 'locks' relates to this answer.
'musical security device protecting' is the wordplay.
I cannot quite see how this works, but
'musical' could be 'hair' (1960s musical) and 'hair' is found in the answer.
'device' could be 'pin' (pin is a kind of device) and 'pin' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'the' acts as a link.
Can you help me to learn more?
(Other definitions for hairpin that I've seen before include "grip?" , "Device for fastening one's locks" , "Nasty road bend or aid to coiffure" , "A very sharp bend, u-shaped" , "Sharp type of bend" .)
