Only difference with an angel is that the feather wings are replaced with bat-like wings.
I was going to say that the horns (and goat-legs) came from "demonizing" the Horned God/Pan/etc deities from Paganism. But looking it up (check Wikipedia on Satan, Devil, Pan, Horned God for references), it turns out that this demonization occurred mostly in the late as the early 19th century, while the image of a horned Devil occurs at least as early as the 13th century. Interestingly, the image of The Devil in the early 18th century Tarot of Marseille seems to have branched antlers, not horns.
And that's just a cursory investigation, the complete story is probably much more complicated than that :) There's some stuff involving the Knights Templar vs ancient Pagan imagery, but I'm done with Wikipedia for the moment :-)
