Front fog lamp wiring

[tim328i]

Help please. I need to replace my front fog lamp, as the glass was broken. However, when I removed the unit, one of the wires had snapped right at the point it joins the l-shaped rubber attachment, which sits inside a white box. As it has snapped right at the rubber, I cannot see how to reconnect the wire.

Is there enough wire to stripe back the rubber from it?
