If I understand you correctly there is nothing in between the individual batteries to prevent 'failure' (like the diode alan suggested). Do you me failure like thermal runaway? Failure like a dead battery (possible)? I'm not sure what you are preventing here, fuses are for overcurrent protection.

Generally though putting them in parallel is a relatively safe bet with sealed lead acid batteries so I doubt there would be any failure to begin (faster aging if anything). Don't combine a old battery with a newer battery in parallel. Make sure the batteries are from the same manufacturer (preferably new). Practice what Alan said about charge and discharge.
