1. A method for use with a heart of a subject, the method comprising:
advancing a tool distally along a flexible elongate contracting member, toward an anchor implanted at the heart, the tool including a cutting element;
applying tension to the contracting member such that the contracting member slides proximally through a fastener disposed at the heart, while a stop is removably coupled to the fastener in a manner that maintains the fastener in an open state; and
using the tool, pulling the stop proximally in a manner that moves the stop both:
away from the fastener, such that the fastener responsively clamps to the contracting member, thereby locking the tension in the contracting member, and
against the cutting element of the tool such that the stop pushes the cutting element against the contracting member in a manner that severs the contracting member.
