Abstract: A coupling device that interconnects a plurality of carts by an extendable end on an elongated member that is movable from a retracted location beneath the cart. The coupling device includes a receiver end to secure with the extendable end of an another cart, but without it interfering with the fold up feature of the cart. The elongated member and the receiver end are part of two separate units that are mounted under a cart at opposite ends of the cart.
