An analysis of the time correlation between Gamma-Ray Bursts from BATSE detector and EXPLORER Gravitational Wave Antenna data was performed from april 1991 to december 1996. A time interval of $\pm 5$ minutes around the trigger time of Gamma-Ray Bursts (GRBs) was explored. No significant excess of coincidences between GRBs and EXPLORER events with an energy of about 100 mK was found. This result allows to exclude correlations with 1 ms Gravitational Wave (GW) bursts with amplitude: $h \ge 2.5 \ 10^{-18}$.

Key words: gravitational waves -- gamma-ray: bursts
