Abstract
An animal trap of a type having pivotal jaws operated by spring loaded actuators which embrace the jaws and which are pivotally mounted on the arms of a U-shaped retention pin is provided with a security device for preventing an animal caught in the trap from pulling out the pin with its teeth and thereby dismantling the trap. The security device is in the form of a tongue upset from a cross frame member of the trap over which the base portion of the pin extends. The tongue engages the outer surface of the pin and prevents axial withdrawal of the pin arms from the actuators.
