A safety device for connecting orderly positioned shopping carts to each other includes a token extractor comprising a control key device which is insertably-releasable from the shopping cart and carries an insert having a token-receiving slot. An encoding ring is positioned on the upper surface of the grip of the cart. A releasing member is resiliently suspended on the cart and serves for connecting one cart to a neighboring cart when the releasing member of one cart is inserted into the encoding ring of the neighboring shopping cart. The releasing element is provided with coding markings and can be inserted into the encoding ring of the neighboring shopping cart in a plurality of various positions corresponding to the markings on the releasing element whereby the shopping carts of one supermarket can be distinguished from the shopping carts of another supermarket located at the same shopping plaza.
