Gas heaters with a collet cylinder connection

Collet

— the design where the heater attaches to a compact canister with a "bayonet" lock and snaps on with one movement is most commonly found in portable camping models. The chuck is valued for its speed and simplicity: plug it in, lock it, and it's ready to go, without keys and adapters, and the canister is easy to carry with you. Compared to a threaded connection, the chuck is typically faster to connect but is often designed for lighter camping canisters and is less "versatile" for larger household tanks. Example: take the heater on a fishing trip and quickly connect it to a standard camping cartridge to warm up by the chair or in a small tent.
