Abstract: A pipe repair device is disclosed which provides a flexible elongate band for encircling the outer diameter of a portion of a pipe or other cylindrical conduit to be repaired. The band is comprised of two components, namely an elastomeric component of an elastomeric material and a tensile component comprised of a material having a high tensile strength and a high modulus of elasticity. Both components are joined at a base end which is connected to a lug assembly having a one-way lock device. The two components of the band extend from the base end along a free end in a loop which encircles the pipe and runs through a slot in the lock device. The lock device captures the band with the tensile component under sufficient tension for compressing the elastomeric component against the pipe to create the fluid-tight seal.
