An apparatus wherein an elongate tube receives a threaded rod therewithin, wherein a medial sleeve including a threaded bore is rotatable to effect extension and retraction of the threaded rod relative to the tube. The tube and rod each include "J" shaped jaw member coaxially aligned with the tube and rod to engage opposed portions of an animal rib cage to effect a spreading of the rib cage subsequent to a hunting procedure. The sleeve may optionally include an annular array of blind bores to slidably receive an elongate peg member to enhance rotation of the sleeve relative to the rod.
