Replace a string containing backslash using sed

Question

I want to substitute a variable SERVICE with a string $service which contains a backslash using sed. I did the following

sed "s/SERVICE/`printf '%q' "${service}"`/g"

Using this I am getting the substituted string as

b_a^c_b_\]Wdd[]X\[X\[W206C?2@,.\\,A@2AW!w6"|

where as I want

b_a^c_b_\]Wdd[]X\[X\[W206C?2@,.\,A@2AW!w6"|

Is there any other way to do it. PS(The string $service has many different special characters)

How do you set the value of the service variable? Your example works fine for me (I do service="a\a", and only one backslash appears in the replaced string). — cabad, Jun 21 '13 at 17:58
The value of $service is `b_a^c_b_]Wdd[]X[X[W206C?2@,.,A@2AW!w6"|` — msd_2, Jun 21 '13 at 18:00

You might as well not use sed at all but just bash like this instead:

while read -r; do
    echo "${REPLY//SERVICE/$service}"
done
