A pair of elongated clamp blocks are joined together in laterally spaced, parallel relationship by means of a pair of vertically spaced clamp screws which serve to move the blocks toward and away from each other. Each clamp block is provided with a transverse slot extending longitudinally inward from one end thereof at an oblique angle with respect to the screws. The blocks are disposed adjacent the outer side of a tank with the slots extending angularly outward away from each other. An elongated flat strap is looped about the tank and each end portion thereof is threaded outwardly through the slot in the associated clamp block, then is bent inwardly around the inner portion of the block facing the other block of the pair, and the terminal portion of the strap end is doubled back between the looped portion of the strap and the outer surface of the tank. The screws then are rotated to draw the clamp blocks toward each other, whereby to tighten the strap about the periphery of the tank.
