Click "add", select the first video, then click "append", then select the other videos to append. You can select multiple videos as long as you select them in order or you can append one by one. Then click "Start muxing". You might want to change the output filename. The other options are not really necessary for basic merging. Nevertheless, you can also add multiples subtitles in various formats or languages and also multiple audio tracks.
avimerge is a versatile tool. It can contatenate several
AVI files into one. It can also be used to fix an index of
a broken file and can also replace audio tracks or muxes
new ones. It can read raw AC3 and MP3 files for multplex-
ing.
Installation
sudo apt-get install transcode transcode-utils
Usage
You can merge avi files with:
avimerge -i input1.avi input2.avi -o output.avi
It's encoding-free, so joining the parts usually doesn't take much longer than a minute.
Options
Other available options are:

Mencoder
You can use Mencoder (Mplayer's encoded), that I recently found as a very good alternative to avconv.
Installation
sudo apt-get install mencoder
Usage
To merge some AVI files to a single AVI file, just call mencoder with setting "copy" as both video and audio encoder, so that no encoding is done:
With this you can merge not only AVI videos, but also every format supported by Mencoder (see Selecting codecs and container formats page).
