An impact tool couples two or more aligned pipes to form a system of aligned pipes in a safe manner. The impact tool has a strut having opposed spaced-apart ends, an impact-delivering plate mounted on the first end of the strut, and an impact-absorbing plate mounted on the second end of the strut. The plates have an outer surface with a co-extensive rubber cover. The strut has two co-extensive elongated members extending between the plates, and a shoe is mounted on the first and second ends of the strut for securing the plates to the strut. The impact tool is heavy and powerful enough to force and couple the pipes together without the need of a sledge hammer and/or additional workmen.
