ABSTRACT:
A respiratory device coupling construction comprises a device which is used for respiration and which contains a cylindrical receiving recess for a connection such as a breathing gas connection. The connection or coupling includes a connector for a conduit of the gas which has a tubular portion which is insertable into the receiving recess. A tubular cover member overlies the cylindrical receiving portion and has a slot therethrough. A U-shaped locking spring has a web portion with an actuating part which is displaceably positionable in the slot so as to project from the cover member for engagement by a person's hand. The U-shaped locking spring includes two leg portions which straddle the tubular portion. Respective legs engage in respective slots on diametrically opposite sides of the tubular portion of the connecting device and the ends of these legs engage against a camming surface defined at the edge of the slot on the tubular portion. When the actuating part is depressed by a person's hand, the cam springs the leg portions outwardly to release the tubular portion for disconnection. When the actuating part is released, the leg portions spring into the slots and hold the tubular portion in the cylindrical receiving recess.
