Measuring device, which we bank on at Easter time? (6,7)

Ross

I believe the answer is:

spring balance

'device which we bank on at easter time?' is the definition.
'spring balance' can be an answer for 'device' (spring balance is a kind of device). I am not certain of the remainder of the definition.

I don't understand how the rest of the clue works.

I've seen this clue in The Guardian.
