An adapter for connecting pullers to conduits of a variety of sizes includes a flexible cable for surrounding the conduit. A surrounding portion of the cable can be adjusted to any desirable length. In one embodiment, the adapter includes a connection plate that has a spring loaded cable connected at one side edge of the plate and a notch at an opposite edge of the plate. The cable includes stop lugs at positions along the cable corresponding to conduits of a variety of sizes. The cable surrounds the conduit and a portion of the cable adjacent to one of the lugs is engaged in the notch. In another embodiment, the connection plate includes a hook at one side edge and a one-way stop mechanism at the opposite side edge. The cable is connected to the connection plate on the hook at one end and the other end of the cable passes through the stop mechanism. The surrounding length of the cable may be shortened by pulling the cable through the stop mechanism and may be lengthened by releasing a lever of the stop mechanism.
