A weldless pipe repair assembly comprises a cylindrical hub member having a through bore, the hub member being formed in two separable, mating parts for slidable interfitting engagement, a first one of the parts having a longitudinal slot for fitting the part transversely over a pipe in the area of a leak or rupture, prior to sliding the second part into engagement with the first part so that the hub member surrounds the pipe. At least one sealing sleeve is designed to fit in the hub bore to seal the space between the pipe and hub member, the sleeve being slit to allow it to fit over the pipe, and a locking assembly is provided for urging the sleeve into the hub member and sealing the sleeve against the pipe.
