1. A reinforcing bar coupling assembly comprising:
a sleeve with an inner surface that encloses at least part of at least one reinforcing bar when coupled with the at least one reinforcing bar; and
at least one pin having a body and two opposing ends fitted with interference between, and causing:
local plastic deformation about, at least part of the inner surface of the sleeve;
local plastic deformation about, at least part of an adjacent outer surface of the at least one reinforcing bar; or
local plastic deformation about, at least part of the inner surface of the sleeve and an adjacent outer surface of the at least one reinforcing bar;
when coupled with the at least one reinforcing bar, where at least part of the body of the at least one pin is in contact with at least part of the inner surface of the sleeve and the outer surface of the at least one reinforcing bar when coupled with the at least one reinforcing bar and wherein local plastic deformation results in mechanical interlocking of the coupling assembly; and
wherein the at least one pin is inserted tangentially and orthogonally to the longitudinal length of the at least one reinforcing bar between the inner surface of the sleeve and the adjacent outer surface of the at least one reinforcing bar when coupled with the at least one reinforcing bar.
