To me, "push on"means "pull off"! In other words, may become disconnected without you noticing! I have made "quick-connect" test equipment cables for BNC, N, bayonet and screw "C"' connectors just for convenience but would never use them for a semi-permanent fixture. Just carefully cut off the retaining ring to leave the 'push-on' part. Obviously doesn't work for PL239/SO259 connectors.
