Mask partner's striking spectacles from assembled onlookers (7)
I believe the answer is:
snorkel
This might be a double definition.
'mask partner's striking' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'spectacles from assembled onlookers' is the second definition.

Perhaps you can see a link between them that I don't see?
Can you help me to learn more?
(Other definitions for snorkel that I've seen before include "Surface breathing tube" , "(Semi-)underwater breathing apparatus" , "Diver's breathing tube" , "diving equipment?" , "Breathing device for swimmers" .)
