Explanation:
A live bolt is a latch, as opposed to a dead bolt.

https://www.timpsonlocksmiths.co.uk/locksmith-terminology/
"Live bolt – See “Springbolt”.
...
"Springbolt – Sometimes called the latchbolt. A bolt having the outer edge shaped by bevelling of the vertical face. It is a bolt which may be pushed back into the lock-case and will return to the extended position without mechanical assistance."

Rather than "loquet", which is really a different sort of latch, this is really a "pêne à ressort"

https://fr.wikipedia.org/wiki/Pêne
"pêne à demi-tour ou à ressort : pêne de serrure dont le bout est en biseau, et qu'il est possible de faire aller et venir sans recourir à la clef"
