A tensioning assembly (1) for winding a winding system (5). The tensioning assembly (1) includes a support bracket (9), a collar portion (13), a ratchet wheel (17), and a pawl component (23). The support bracket (9) is connectable to a fixed frame. The collar portion (13) is removably mountable onto a shaft (3) of the winding system (5), and is proximate to the support bracket (9), the collar portion (13) having a securing assembly (15) for removably securing the collar portion (13) onto the shaft (3). The ratchet wheel (17) is securely mounted onto the collar portion (13) and is rotatable therewith, the ratchet wheel (17) being positionable adjacent to the support bracket (9), and being provided with a plurality of teeth (19) and a plurality of corresponding recesses (21). The pawl component (23) is operatively mountable on the support bracket (9) and is moveable with respect to said support bracket (9), the pawl component (23) having an extremity (25) being positioned, shaped and sized with respect to at least one recess (21) of the ratchet wheel (17) for allowing rotation of the shaft (3) along a winding direction (7a), and for blocking rotation of the shaft (3) along an unwinding direction (7b).
