Adjustable tensioning means for mechanical parts, particularly ski bindings. In a mechanical device such as a releasable ski binding having a backing abutment at one end thereof and an anchoring or locating means at the other end thereof, variation in tension can be provided by locating one or more inserts, such as washers, between the spring and either the abutment or the locating or anchoring means. Such washers are, in this invention, provided with nesting contours such that the washers can be inserted into or released from operating position only by partial retraction of the spring and axial movement of the washer. In some embodiments the inserts are movable mounted for insertion or removal by a lateral motion.
