A manual bundling tool has a first operating means that positionally shifts relative to a tool body opposite a handle. A tightening mechanism pulls an other end of a cable tie band in relative to a head part by positionally shifting the first operating means. A holding mechanism holds the other end side of the band part pulled by the tightening mechanism so as to prevent return movement. A second operating means positionally shifts relative to the tool body. A securing mechanism secures the other end side of the band part to the one end side of the band part in response to positionally shifting the second operating means. A release operation means positionally shifts relative to the tool body and a release mechanism releases the hold on the cable tie band part by the holding mechanism in response to a positionally shifting the release operation means.
