Abstract: A tank cinch is configured to cooperate with a strap to secure a tank of compressed air to a buoyancy compensation device. The tank cinch includes an adjustable frame having a sliding member, a first cam receiver and a second cam receiver. A lever body including a first cam and a second cam is pivotably joined to the adjustable frame and is pivotable about a pivoting axis defined by the adjustable frame. The lever body is configured to fix a first end portion of the strap. The adjustable frame is configured to fix a second end portion of the strap with the sliding member when the lever is rotated about the pivoting axis towards the adjustable frame member. The cams are arranged to bear against an outermost surface of the tank and to be received in the cam receivers when the lever body is pivoted towards the adjustable frame.
