Clipping is when samples exceed the maximum range of the format and so the peaks of the sound get cut off. Other people have posted explanations of how to deal with that, but I don't think it's really the question you're asking - you're asking what happens when you get a
click (not "clipping" under the technical meaning of the term) where one piece of sound ends and the next begins.
Those clicks are caused by breaking the waveform and picking it up at a different point in the range, so there's a sharp jump. You can reduce the effect by applying a low-pass filter, but that has obvious problems. A better idea is to zoom in, look at the waveform in high resolution, and adjust the in/out points so that the levels match when you go from one sound to the next. It's convenient to cut all your clips where the waveform crosses zero, but on an individual transition you could get away with cutting at some other level as long as they match.
For a better sound (as I think someone mentioned) you could also look at doing some kind of cross-fade.
