ABSTRACT OF THE DISCLOSURE A soil pipe coupler. There is an annular por- tion formed from an elastomer having a hardness of 95 on the Shore Durometer A Scale. A ridge is formed about the portion's inner surface to be inserted between the ends of the two pipes to be coupled. A clamp means is included and clamping sleeves formed from an elastomer having a hardness of 95 on the Shore Durometer A Scale are formed integrally with the annular portion. The clamping sleeves extend axially from either side of the annular portion to overlap a length of each pipe to be joined. Each of the clamping sleeves is formed with an annular groove on the outer surface to position a clamp. The annular grooves have a ridge to support a clamp whereby the pipes to be coupled are inserted into the clamping sleeves until the pipe ends abut the ridge of the annular portion. The clamping means are tightened to shrink the clamping sleeves about the pipes to be coupled. -22-
