Abstract: A diving tank handle is disclosed, for selective attachment to a cylindrical diving tank. The apparatus includes a clamping ring for slideably engaging the peripheral surface of the diving tank in an unclamped state and for frictionally engaging the peripheral surface of the diving tank in a clamped state, the clamping ring having an open side with a pair of opposed end surfaces. The apparatus further includes a cam pivotally mounted to the clamping ring between the opposed end surfaces, on a pivot axis perpendicular to the cylindrical axis of the diving tank. The apparatus further includes a handle portion mounted to the cam for clamping the ring to the diving tank by rotating the cam. The diving tank handle may be easily slipped onto the diving tank with the handle portion in the clearance position, compactly stored while mounted on the diving tank with the handle portion in the storage position and the diving tank conveniently carried with the handle portion in the lifting position.
