In a shopping cart comprising an undercarriage, a handle having two tubular portions extending generally upwardly from the undercarriage, and a basket mounted to the undercarriage and the handle, the basket has a gate hinged to the tubular portions of the handle via a hinge wire extending along an upper edge of the gate. Two tubular sleeves are fixed to the handle, each extending through an inwardly opening aperture in an associated one of the tubular portions of the handle. Each end portion of the hinge wire extends into one of the tubular sleeves. Two rivets are fixed to the handle, each having an outside head, a tubular shank extending inwardly through an outwardly opening aperture in an associated one of the tubular portions of the handle and through an associated sleeve, and a mandrel drawn outwardly into the shank so as to expand the shank and the associated sleeve. As disposed within the tubular portions of the handle, the mandrels of the rivets permit but limit axial movement of the hinge wire relative to the tubular sleeves, the tubular portions of the handle, and the retaining structures. In one contemplated embodiment, each tubular sleeve has an annular flange bearing against an outer margin of an associated one of the outwardly opening apertures. In an alternative embodiment, each tubular sleeve has an outer end portion disposed within one of the tubular handle portions of the handle.
