Try ITA's Airfare search

As with other airfare searches, you can only filter by total travel time. But on the results page, you can choose to view results by "Time Bars," which give you a graphic representation of the time spent on each flight. It lets you quickly identify the options that suit you.
► Complete trips► Individual flights► Time bars
ITA isn't an agency, so you need to buy the flights elsewhere.
Speaking for myself, I've never found it particularly helpful to split journeys in this way. I find it best to rip the elastoplast off in one go. But YMMV.
