The command:

$ rename 's/--/-/g' *

does not work on my side as it works on yours, maybe it is different
software.     

You do as following in the top directory:

for i in $(find . -type f -iname "*--*"); do mv $i $(echo $i | sed -e "s/--/-/"); done

You may alias the command to:

alias renamedashes='for i in $(find . -type f -name "*--*"); do mv $i $(echo $i | sed -e "s/--/-/"); done'

and invoke it with

$ renamedashes

in future.
