A pair of arms are pivoted together by one end thereof and normally urged apart by a heavy-duty spring. A flexible snare consists of a snare loop and a free or standing end passing through a ring on one end of the snare in a form of a running noose. The free end passes through an eye of the other end of one of the arms and is secured to a trigger lever pivotally mounted on the other end of the other arm. A trigger loop is pivoted to the one arm and in one position holds the trigger lever with the trap in the set position and engages the other arm with the trap in the locked position. When in the set position, a pull on the noose displaces the trigger lever slightly so that the spring pressure between the two arms springs the trap and tightens the noose.
