1. 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 defining an external shape of the male connector, the perimeter wall including a proximal edge and a distal edge;
wherein the male connector defines an insertion axis along which the male connector is receivable into the corresponding female port, said insertion axis extending from the proximal edge to the distal edge; and
wherein the distal edge of the perimeter wall comprises a first distal edge portion which is substantially perpendicular to the insertion axis and defines a single first conduit to transport breathing gas, and a second distal edge portion which is inclined with respect to the insertion axis and defines a single second conduit to transport breathing gas, and
wherein the first distal edge portion extends further from the proximal edge than the second distal edge portion, such that 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.
