A snap-action closure is provided with a body for being mounted on a container and with a cover hinged to the body. The closure includes two spaced apart connecting elements. Each connecting element is joined to the body with a first hinge and to the cover with a second hinge so as to locate the connecting elements offset on one side of the main hinge axis when the cover is in the open position. Each connecting element has a generally linear configuration adjacent the cover and body when the cover is in the closed position and has a non-linear configuration lying generally in a plane parallel to the main hinge axis when the cover is in the open position.
