The connector includes a base and at least two pot engaging parts extending from the base. Each of the engaging parts has a surface adapted to face the wall of a pot, a first engaging member extending in a plane substantially parallel to, but spaced from, the engaging part surface, and two second engaging members extending in a direction opposite to the direction of the first part. The second engaging members are spaced from the first engaging member such that the wall of a pot may be situated between the first engaging member, on the one hand, and the two second engaging members, on the other hand. The second engaging members each have a pot wall contact portion. The contact portion of each of the second engaging members is inclined toward the first engaging member and away from the engaging part surface to accommodate the curvature of a pot wall.
