You need some additional quoting:
for i in *-*; do mv "$i" "`echo $i | sed -e 's/ - /: '`"; done
... works for me.

^^ Did you mean $_ here?

Yes, because Perl doesn't normally automatically iterate over its input;
you can do it manually, or various switches, like -n, cause it to do so.
tr/// is the wrong operator to use, too; see 'perldoc perlop'.
This works:
ls -1 | perl -wne 'chomp; ($new=$_) =~ s/ - /: / and rename $_, $new'
You could also opendir() and readdir() yourself, though that's probably
too much effort for a one-liner. And, as somebody else has said, you
might as well just use the rename(1p) utility that comes with Perl.

Look for the recent discussion on this list on the use of find and
xargs.
