Yes there is a coupling available to connect two lengths of corrugated pipe together. You can also buy a 10' section of the pipe with a coupling as part of the pipe. Both are available at your big box stores like Lowe's and H. Depot.
As for the girls driving over it, you could always buy a section of 4" schedule 80 PVC and join the two with a PVC to corrugated pipe connector. This will be much stronger than the corrugated pipe.
The other option would be to plant a small tree near the pipe that will help avoid anyone driving up on the sidewalk and therefor over the pipe.
