    I'll reply with the same question.

    Here's one for underground, pvc to clay:

    Here's a shielded coupling for above ground, but I can't tell if it can also be used with clay:

    The P3000 series shielded coupling is EPDM for cast iron. Can it be used for clay?

    A number of companies make the all rubber couplings for clay to plastic. Cut out the bad clay then whack off a chunk of plastic a hair less than the length of the gap. The couplings will slide over the plastic so you can set it in place and slide the couplings into position.
