A tensioning unit 10 for a strapping machine serves for the tensioning and sealing of a band 18 guided around an item which is to be strapped. It has a tensioning head 20 and a housing 22 accommodating the same. The tensioning head 20 comprises a tensioning device 24 and a clamping and sealing subassembly 26. Toward the end of a respective tensioning operation, it can be displaced relative to the housing 22 in a band- running direction B, which is counter to the tensioning direction S. Also provided in the housing 22 is a band guide 40 which is arranged downstream of the clamping and sealing member 26, as seen in the band-running direction B, and is subdivided into a front and a rear band-guide part 40' and 40", respectively. In this case, only the front band-guide part 40' can be displaced, together with the tensioning head 20, relative to the housing 22, whereas the rear band-guide part 40" can be moved away generally transversely to the band-running direction B by the front band-guide part 40', which is moved in the band-running direction B, preferably counter to a spring force.
