摘要

Safety system comprises first (100) adaptor, connected to gas oven, and second adaptor. Second adaptor includes body (2), coupling plate (4), intermediate element (3), and arc-shaped aperture (24). Safety element (6) and one end of spring (7) can be inserted in aperture. Safety element can be moved upwards and downwards due to spring. Safety element avoids rotation of coupling plate, hence avoids release of second attachment.
