The trivial extensions of a quasi-abelian category by means of a fully exact endofunctor are again quasi-abelian. Using the one-to-one correspondence between quasi-abelian categories and tiltings, it is shown that the trivial extension of a quasi-abelian category corresponds to a trivial extension of the associated tilting. As an application, a criterion for tilting modules over an arbitrary ring R to be liftable to a tilting module over a trivial extension ring R (sic) M is given.
