Not sure but that repair might be OK if it is a steel line. The rubber hose might just be there to prevent the line from rubbing against the pan (not sure that's the oil pan). Mine has a bit of rubber hose attached over the steel line on the passenger side at an elbow; just saw it when I climbed under to inspect the alternator.

If however all you have there is rubber hose, I agree that it needs to be replaced.
