Abstract: A hairpin spring type trap includes a pair of arms normally urged apart by the spring situated at the inner ends thereof. A cable loop is secured by one end to the distal end of one arm and passes through a guide loop in the distal end of the other arm and is secured to a bracket or clip slidable along the arm through which said loop passes. Ths bracket is frictionally adjustable along the length of the arm when the trap is in the set position. A trigger is pivoted on the other arm and a setting plate extends from the one arm towards the other arm. This plate is provided with opposed jaws on the distal end thereof. When set, the bale of the trigger engages one jaw and the lower arm engages the other jaw with the spring pressure retaining the trap in the set position. Pivotal movement of the trigger in either direction release the trap. If the trigger is swung upwardly against the one arm, the trap is held in a safety position.
