How can I fix my clay drainage pipe?

Whilst digging a new flower bed I came across a drain pipe that has a broken off cuff. The gap is approx 2". The pipe is for surface water and is broken about 18" away from the house. Does anybody now what I can do. I understand that I can get a sleeve to wrap around the pipe and strap it on to keep it secure, but have been having problems finding one.

Any ideas, please.....
