I did have an old caliper in my 'old tat' box of jumble bits. Not sure if it's still there though. I'll have a look for you in the morning - if I remember! There's probably a spring (or 2) on it.
Found it - but it's a totally different design! Sadly the spring is nothing like yours so I'm going to have to say - 'I'm out!'
Mind you, what this has done, is make me investigate what I have actually got! There is a 'GB' engraved on it but no 'Coureur' and I think the number is actually '88' so I'm a bit mystified
It looks more like a Weinmann caliper TBH.
Today is the yesterday of tomorrow.
