I think this is Caesalpinia decapetala
from Caesalpiniaceae family.
Shrubby climber. Common thorny hedge plant.
Photos taken on the outskirts of Pune city(Maharashtra)Near Khed Shivapur.
Initially I thought it to be Caesalpinia bonduc.
but later on I took out the seeds from the pod (which is also very similar)and confirming from the books it appears to be Caesalpinia decapetala
