A strapping tool is disclosed of a type used to apply a steel strap in a tensioned loop around a package and to join the strap via a series of interlocking joints comprising interlockable shoulders punched into overlapped ends of the strap. A base of the strapping tool extends longitudinally and defines a pair of recesses. A frame upstanding from the base is mounted integrally to the base. In a mechanism for admitting the overlapped ends into the tool, for retaining the overlapped ends, and for releasing the overlapped ends from the tool, a pair of latches having hooked ends are mounted pivotably to the base so as to be pivotable between closed positions wherein the latches are positioned with the hooked ends extending into the recesses to retain the overlapped ends between the latch and the base and between the hooked ends and the frame and opened positions wherein the latches are displaced angularly from the closed positions to admit the overlapped ends into the tool and to release the overlapped ends from the tool. The latches are biased into the closed positions. Coacting elements including a lever, which can be manually squeezed toward an actuating handle of the strapping tool, and a camming member, which is arranged to cam the latches, are provided for pivoting the latches from the closed positions into the opened positions.
