Apparatus for locking shopping carts together in nested series at a cart parking station comprising mechanism adapted to be mounted on the handle of a cart adapted for releasably locking therein a latch bar on a tether which is attached to the next cart in the nested series, and a method of utilization of the apparatus for encouraging cart return by customers of the establishment using carts with the apparatus. A first phase of the invention involves an arrangement of a slide thereof and a slide-biasing spring for size reduction. A second phase involves an arrangement for mounting the mechanism on the handle of a cart with the slide extending either longitudinally or transversely of the handle. A third phase involves an arrangement for utilization of the mechanism either as a check-controlled mechanism or in the stated method.
