A strapping unit for wrapping a tightening strap around a packaged item has a base plate, a tensioning device, a sealing device and separating means. The base plate is provided with a bearing surface for arranging on a packaged item. The tensioning device with which a strap tension can be applied to the tightening strap is provided with an actuable tensioning tool which can be brought into contact with the strap. The tensioning tool is being fastened releaseably to the strapping unit by at least one fastening means. The sealing device is provided with a single- or multi-part sealing tool with which two strap layers can be connected permanently to each other by contact with the strap. The sealing tool is being fitted on the strapping unit by at least one releaseable, further fastening means. The separating means with which the strap can be severed has a blade which can be brought into contact with the strap. At least part of the separating means is being fitted releaseably on the strapping unit by at least one further, releaseable fastening means. A plurality of the fastening means are of a design which enables said fastening means to be actuated by the same tool. Worn parts can therefore be swapped with very little maintenance effort.
