A testing head for respirator and diving masks has a form approximating the human head with at least one air conduit traversing the head inside, wherein the testing head has an opening preferably in the area of the mouth, to which the air conduit is connected with its one end, while its other end can be connected with air supply or air exhaust or else testing devices. The testing head has a covering of elastically pliable material which at least partially encloses the head pressure tight on its exterior, wherein the mentioned opening is recessed, and wherein the testing head has a compressed air line which connects the intermediate space between the head and the covering with a compressed air supply for inflating the covering.
