Using approximate techniques we study the final moments of the collision oftwo (individually non-spinnning) black holes which inspiral into each other.The approximation is based on treating the whole space-time as a singledistorted black hole. We obtain estimates for the radiated energy, angularmomentum and waveforms for the gravitational waves produced in such acollision. The results can be of interest for analyzing the data that will beforthcoming from gravitational wave interferometric detectors, like the LIGO,GEO, LISA, VIRGO and TAMA projects
