Narrative:

Weather was clear; visibility unlimited. A baron was [on a] VFR practice ILS approach to 17R; straight in and established. An E170 was inbound from the east for 17L. The E170 was cleared for the visual approach 17L; they read back 17L and were told to square the base to final to allow a slower single engine to land. I think the E170 was so used to landing on 17R that they went through the 17L final for the right side. My trainer quickly keyed up local and told them to watch the E170 as both the baron and E170 were on the tower. Targets appeared to merge with 100 ft vertical separation. The E170 turned hard left to continue for 17L and landed without incident. Recommendation: good techniques to ensure that pilots don't make a mistake were discussed after the training session. The biggest recommendation was to point out the traffic on approach to the parallel when one of the aircraft is based and it looks like he'll be pointing right at them.
