PROBLEM TO BE SOLVED: To provide a holding plug for a manual tightening tool having a lower holding member built therein. SOLUTION: The lower holding member is integrally formed on an upper surface part of the lower holding member at the level above an upper top part of a tooth of the lower holding member, and has an upright or upwardly protruded lip part for forming a specific space between an upwardly protruded tooth of the lower holding member and a lower surface part of a lower end of overlapping ends of a tightening material when an upper tension wheel is retracted from the engagement position with the lower holding member. In this method, the manual tightening tool, in particular, a base part member and the lower holding member can be easily released and disengaged from the engagement position of the overlapping end of an article to be tightened, a packaging container and the tightening material. In addition, when a lip part of the lower holding member is corroded or abraded, the lower holding member can be easily disengaged and replaced by installing a friction spring in the base part member of the manual tightening tool.
