Nope not shimano, Suntour which use to be a competition for shimanoConnecting links are now the norm. With the very high tolerances of modern chains, connecting them by pushing through a rivet is worse than any deficiency of connecting links.
FWIW, Shimano made one back in the late 70's(?) but it never caught on. They have only recently gone back to them after sticking with the special pins for decades.
