A clamp for repairing a damaged pipe member. Shell members are matingly engaged around the damaged pipe member. Segmented inserts are received in a complementary annular channel formed in an inside face of the shell members to form a ring assembly supporting annular seals between the ring assembly and the damaged pipe member. A shell-sealing annular channel is formed between the ring assembly and the shell members to receive a liquid sealant to form an annular seal between the ring assembly and the shell members. A longitudinal channel is formed in longitudinal faces of the shell member to form longitudinal seals in the shell assembly when a ring assembly is disposed at either end of the shell members. The ring assemblies support seals against the damaged pipe member, including a pipe-sealing annular channel formed between each ring and the damaged pipe member between inner and outer annular seals for receiving a liquid sealant. The pipe-sealing annular channels, the shell-sealing annular channels and the longitudinal channels are in fluid communication to facilitate filling with the liquid sealant.
