  We prove the lack of asymptotic collisions between particles following the
Cucker-Smale flocking model with a bonding force and its simplification.
Moreover, we prove that in the case of the CSB model with a singular
communication weight, finite-in-time collisions are impossible. Consequently,
we establish existence of the global-in-time minimal distance between the
particles. Furthermore, we show that asymptotic distribution of particles is
confined within a ball of a given radius.
