Apparatus is provided, including a tissue-adjusting member selected from the group consisting of: one or more artificial chordae tendineae and at least a portion of an annuloplasty ring structure. The tissue-adjusting member includes an adjusting mechanism that is configured to adjust a tension of the tissue-adjusting member. The adjusting mechanism includes a locking mechanism configured to restrict adjusting of the tissue-adjusting member by the adjusting mechanism. An elongate member is configured to maintain the locking mechanism in an unlocked state during adjusting of the tension of the tissue-adjusting member by the adjusting mechanism, and facilitate locking of the adjusting mechanism by the locking mechanism. A tool is configured to facilitate actuation of the adjusting mechanism to adjust the tension of the tissue-adjusting mechanism. The elongate member and the tool are slidably coupled with respect to each other. Other applications are also described.
