This seems a popular simple question. We had it last year (with its
endless discussions, of which I'm guilty too 8-). Any chance that this
one is added to the 'list of simple questions & answers', Chris?

|mv $i `sed -e 's/flip$/flop'`

You probably meant here:

mv $i `echo $i|sed -e 's/flip$/flop/'`

As it stands, the sed command has no input (well, not what you expect
it to have), and the sed expression contains a syntax error.

Suggestion: move the sed command to the for command, so that you can do
all substitutions all at once:

for i in `echo *.flip|sed 's/\.flip / /g;s/\.flip$//'`
do
	mv $i.flip $i.flop
done

Or, without a loop:

apply 'mv %1.flip %1.flop' `echo *.flip|sed 's/\.flip / /g;s/\.flip$//'`

(Apply(1) is probably BSD-only).

Or:

apply 'mv %1.flip %1.flop' `ls *.flip|sed 's/\.flip$//'`

Or:

(etc, etc, ... )
