Most RCA splitters and patch cords are designed for use with stereo/audio components and ARE NOT DESIGNED TO CARRY MUCH CURRENT. These are typically referred to as “shielded” meaning the negative conductor is composed of a braid of tiny wires which shields the center + wire from electrical noise. Unfortunately these tiny wires can’t carry much current and if used with dew heaters they will get hot and may even melt and short out. If you need a splitter or extension it is best to make your own using #24AWG (small heaters) to #18AWG (larger heaters) wire.
