Abstract
Apparatus for removing piping from the ground comprises a cable (1) which has pipe engaging means (2) disposed along its length. The pipe engaging means (2) are arranged such that the cable (1) is insertable into a pipe (3) in one direction but that attempted withdrawal of the cable (1) in the opposite direction relative to the pipe (3) causes the pipe engaging means (2) to jam the cable (1) in the pipe (3). The pipe (3) can then be pulled from the ground, the pulling force being distributed along the length of the pipe (3).
