An anesthetic supply system, safety valve coupler for selectively connecting a conventional anesthetic hose fitting to anesthetic gas delivery means adapted to be connected to a breathing passage of a patient, said valve coupler comprising: anesthetic gas delivery means adapted to be connected to a breathing passage of a patient and having a gas inlet port, an adapter member having a first end including means connected to said gas inlet port of said delivery means and a second end and a fluid passage between said first and second ends; a valve member having a first end with connector means for connecting said valve member to a conventional hose fitting of an anesthetic supply system and a second end with connector means for connecting said valve member to the second end of said adapter member, said valve member including an internal valve means with an acutuator member contacting the second end of said adapter member for opening said valve means on connection of said valve member to the adapter member, and closing said valve means on disconnection of said valve member from the adapter member, said adapter member being proximally located with respect to said delivery means when connected for minimizing gas contamination of the environment when said adapter member and delivery, means are separated.
