The present invention provides a tensioning device (40) for a compensating sheave. The compensating sheave is provided with a housing (2). The tensioning device (40) comprises: a first snap-fit member (3); a second snap-fit member (8); and a trigger mechanism comprising a resilient assembly and a limiting assembly, wherein the limiting assembly is provided with a limiting member (4), wherein the tensioning device (40) has a first state in which the limiting member (4) abuts against a second end (32) of the first snap-fit member (3) so that a certain clearance is kept between a first end (31) of the first snap-fit member (3) and the second snap-fit member (8) and a second state in which the limiting assembly is moved downward so that the first end (31) of the first snap-fit member (3) is rotated downward until the first end (31) is snap-fitted with the second snap-fit member (8). The tensioning device (40) has better replaceability, is convenient to install and remove, and occupies less labor, material and time costs.
