A device for splicing two belt ends together, the device having a first outer clamping plate, a second outer clamping plate, and a central plate disposed between the first and second outer clamping plates. Each of the first and second outer clamping plates includes inwardly facing surfaces oriented toward the central plate. Gripping surfaces of the devices are improved. A first gripping region is disposed on the inwardly facing surfaces of the first and second outer clamping plates, the first gripping region having a plurality of rows of teeth. A second gripping region is disposed on the inwardly facing surfaces of the first and second outer clamping plates and includes spaced apart elongated recesses positioned parallel to a long axis of the first and second outer clamping plates. A wedge member, to accommodate different sized and shaped belts, is removably coupled to an end of the central plate.
