  • Patent number: 5890635
    Abstract: A carrying attachment includes a clamping member and a retaining member. The clamping member includes a lug portion with a flat major surface, and left and right jaw arms which extend from the first lug portion and which are of a dimension sufficient for flexing toward each other. Each of the jaw arms includes a clamping segment that defines an inner clamping wall transverse to the flat major surface, and a first outer wall. The inner clamping walls of the clamping segments of the jaw arms are shaped so as to clamp a constricted part of a container therebetween. A hook end portion extends from the clamping segment and defines an inner wall and a second outer wall which are transverse to the flat major surface and which form deflection junctures with the inner clamping wall and the first outer wall. The hook end portion has a snapping protrusion that extends from the second outer wall in a direction opposite to the inner wall.
