A strap attachment device includes a main body with a lower body end that has an opening suited for a strap. Based on its position, a cam lever at the opening of the lower body end holds or releases the strap, permitting adjustment of the length of the strap that enters the opening. Extending upward from the lower body end is an upper body end that is curved into a hook or any other shape appropriate for connection to an object. A flexible or translatable gate may extend from the main body so as to prevent the upper body end from inadvertently becoming detached from the object. Slip-resistance on the upper body end resists slippage between the upper body end and the object during side-to-side movements. Ends of the strap may include a loop or handle or connect to other devices.
