The author defines 2-gerbes bound by complexes of braided group-like stacks. Then, a classification result in terms of hypercohomology groups with values in abelian crossed squares and cones of morphisms of complexes of length 3 is established. Applications to the geometric construction of certain elements in Hermitian Deligne cohomology groups are also given.
