No experience with those retainers here, but I would personally reinforce
it with a coupler unless you're going for an altitude record. What's the
peak thrust on your motor? You could always test it's strength by putting
it onto concrete, placing a thick piece of wood over it, and getting two
people to stand on it (or weight a few buckets filled with rocks)
