A spring-loaded receptacle designed to accept and reversibly link a stringer spike to an angler or watercraft to collect and combine fish. The sheath is a dual lumen device comprised of an outer tubular shell, a vertically movable, hollow inner stem, and a helical spring about the lower portion of the inner stem. The inner stem manifests three holes drilled at 120 degrees from one another and beads placed in these holes for engaging and securing the spike. A conically shaped bead deflector skirts the inner stem, surrounds the bead system, and exhibits a widening circumference as it descends into the outer shell. Spike insertion is accomplished by depressing the stem, compressing the spring, and allowing bead movement downward and outward away from the sheath center. The beads grip the spike when the stem is released, the spring expands, and the beads move into the bead deflectors tapered angle.
