A figure eight descender for rappelling with a rope includes a first loop, a second loop, a neck connecting the first loop and the second loop, and a clip attached on the neck. The clip surrounds the rope so that the clip contains the rope between the first loop and the second loop, preventing the rope from sliding over the first loop or the second loop. The clip has a U-shaped body, and the body has a first end and a second end. The first end is supported by a hinge provided on the neck so that the body can pivot around the hinge, and the clip is spring-biased so that the second end is forced toward the neck.
