Connection apparatus for breathing apparatus

A connection apparatus for connecting breathing gas delivery components of a breathing apparatus, comprising:

• a male connector configured to be received in a corresponding female port, the male connector comprising a perimeter wall which defines an external shape of the male connector, the perimeter wall enclosing first and second conduits to transport breathing gas;
• wherein the male connector defines an insertion axis along which the male connector is receivable into the corresponding female port;
• wherein the perimeter wall comprises first and second wall portions which taper together such that a first edge of the first wall portion and a first edge of the second wall portion are connected at an apex portion;
• wherein the perimeter wall comprises a first distal edge portion defining the first conduit to transport breathing gas and not defining the second conduit to transport breathing gas, and a second distal edge portion defining the second conduit to transport breathing gas and not defining the first conduit to transport breathing gas;
• wherein the first distal edge portion is substantially perpendicular to the insertion axis and the second distal edge portion is inclined with respect to the insertion axis;
• and
• wherein the first distal edge portion is received in the corresponding female port prior to the second distal edge portion being received in the corresponding female port.
