Connectors for connecting components of a breathing apparatus

A connection system for connecting a first air delivery conduit to a port or a second air delivery conduit, the connection system comprising:

• a male connector adapted to be connected to a first component selected from the first air delivery conduit, the port or the second air delivery conduit, the male connector having a recess;
• a female connector adapted to be connected to a second component selected from the first air delivery conduit, the port or the second air delivery conduit, the female connector having an outer wall, at least a portion of which is axially retractable, and an engagement device configured to engage the recess,
• wherein the male connector is configured to be insertable into the female connector to form a connection between the first component and the second component, and
• wherein the engagement device is biased toward a central portion of the female connector when the outer wall of the female connector is in an extended position and is biased toward an exterior of the female connector when the outer wall of the female connector is in a retracted position.

A connection system for connecting a first air delivery conduit to a port or a second air delivery conduit, the connection system comprising:

• a male connector;
• a female connector having an outer wall, at least a portion of which is axially retractable,
• wherein the male connector is configured to be insertable into the female connector to form a connection,
• wherein the male connector and the female connector are configured so that the male connector is removable from the female connector when the outer wall of the female connector is retracted and so that the male connector is not removable from the female connector when the outer wall is extended, and
• wherein the outer wall of the female connector is configured to automatically retract and extend upon insertion of the male connector into the female connector.
