A hook for tree or branch shakers comprises a main body connectable to a reaction rod of a shaker, a main gripping expansion piece extending transversely from the main body and susceptible of engagement with a branch, and a complementary gripping expansion piece that, in co-operation with the main gripping expansion piece, defines a gripping space; the hook further comprises means for generating constraining and/or gripping reactions that can be directly activated between the branch and the reaction rod under operating conditions. |
