A strap tensioning device comprises a frame (1) with a rotatable reel (3) and a turnable command means (2). A ratchet wheel (43) is co-rotatively connected with the reel, said wheel cooperating with two spring-loaded latch elements (14, 29). When the command means (2) is turned out from the frame (1), the reel (3) is carried with it. At an opposed return movement, the reel (3) is blocked. A rotatable support roller (4) is arranged between the two side pieces (5, 5') of the frame (1). The reel (3) comprises a shaft (16) whose opposed ends are arranged in elongated holes (9). In this way, the reel (3) may be distanced from the support roller (4), whereby the device may be used for both strap tensioning and strap feeding.
