The invention is a clamping device for securing photographic equipment, which includes a mounting plate to a supporting structure, such as a tripod and or to a strap. The device includes a pair of opposed sliding clamps operably attached to a base. The clamp engages opposite sides of the base and may each be moved independently of one another to secure the supporting structure and to provide the capability to adjust to small variations in mounting plate sizes between equipment brands. The device has a loop to connect a strap or a strap connector.
