Petzl's Ok Triact Lock, an oval carabiner for use with a pulley.

The OK carabiner is designed for just that.
It is also very practical at belay stations.
Symmetrical shape for use with belay devices, to maximise efficiency no matter which end is closest to the device.
Oval shape works really well with pulleys.
