Abstract
A cylinder band for immobilizing an air cylinder on a buoyancy regulator includes a belt, a buckle and a coupler adapted to couple the belt and buckle. The buckle has a pair of parallel supporting walls, which have longitudinally opposite first ends and second ends. A pivot extends through the first ends, with end surfaces thereof defining cam surfaces that enhance a tensity of the belt as the second ends swing around the pivot while the end surfaces are in contact with the peripheral surface. The end surfaces each has a pair of convexly curved surface segments spaced from each other in the circumferential direction of the peripheral surface, which are adapted to contact the peripheral surface at once. A concavely curved surface segment extends between the convexly curved surface segments and has a curvature radius which is the same as or less than a radius of the peripheral surface.
