Abstract
A headgear connection assembly for a respiratory mask is configured to provide easy use and a reliable connection. The headgear connection assembly may include a clip attachment portion and a clip. The clip may include a hook, a headgear attachment loop, and one or more finger grips. The hook may be configured to include a central portion and two outer portions and an interference bump and to engage with a post of the clip attachment portion. The central and outer portions of the hook may be configured to flex independently of one another. The clip attachment portion may include geometry to limit rotation of the clip.

A clip connector for connecting a headgear to a mask body, comprising:
- a body portion configured for attachment to the headgear;
- and
- a hook portion, the hook portion defining a U-shape having a first leg, a second leg and an entrance to a space between the first leg and the second leg, the hook portion comprising:
- a central portion;
- a pair of outer portions positioned on opposing sides of the central portion, wherein each of the central portion and the pair of outer portions define a portion of both the first leg and the second leg;
- and
- an interference bump on at least one of the central portion and the pair of outer portions, the interference bump extending into the entrance to the space;
- wherein the hook portion is formed as a single piece, and wherein each one of the central portion and the pair of outer portions is configured to flex independently of any other one of the central portion and the pair of outer portions.
A respiratory mask configured to deliver pressurized gas to a user, the mask configured to attach to headgear by a connector clip having a body portion and a hook portion, the respiratory mask comprising:
- a post configured to be received within a space of the hook portion of the connector clip;
