Double spring traps such the conibear trap are difficult to set due to the heavy duty hairpin type springs on either side thereof. The present device consists of a crank, a length of cord or cable extending from the distal end portion of the crank and a spring ring anchor bar on the distal end of the cord or cable. The bar is fed downwardly through the upper loop and then through the lower loop and is positioned so that it cannot disengage from the lower loop. The crank is fulcrumed across the top loop and rotated thus winding the cord or cable about the distal end portion of the crank which shortens the cord or cable and gradually and safely pulls the two loops together so that the detachable locking clip normally provided, can be engaged over the arms to hold them in this position. The other spring is treated in a similar manner thus rendering the trap inoperative for baiting and setting purposes whereupon the clips can be removed.
