Summary: Using the coincidence degree theory by Mawhin, we prove the existence of periodic solutions for the second-order delay differential equations with impulses $$\displaylines{ x''(t)+f(t,x'(t))+g(x(t-\tau(t))=p(t),\quad t\geq0,\; t\neq t_k,\cr \Delta x(t_k)=I_k(x(t_k),x'(t_k)),\cr \Delta x'(t_k)=J_k(x(t_k),x'(t_k)). }$$ We obtain new existence results and illustrated them by an example.
