A clip assembly for retaining a mask cushion to a mask frame, the clip assembly including a main body having a resilient detent movable between a first position in which the detent is relatively uncompressed and a second position in which the detent is relatively compressed, whereby in the second position the detent is configured to be guided through a slot located on the frame, and, upon insertion, the detent is releasable so that the detent assumes the first position in which the detent is lockable relative to the slot of the frame.
A mask assembly comprising:
- a mask frame having a slot;
- a mask cushion provided to the frame;
- and
- a clip assembly for retaining the mask cushion to the mask frame, the clip assembly including a main body having a resilient detent movable between a first position in which the detent is relatively uncompressed and a second position in which the detent is relatively compressed, whereby in the second position the detent is configured to be guided through the slot, and, upon insertion, the detent is released such that the detent assumes the first position in which the detent is locked relative to the slot.
A clip assembly for retaining a mask cushion to a generally triangular mask frame having a base side, the clip assembly including a generally triangular shaped main body defining a base portion corresponding to a base portion of the frame and two side portions forming an apex, the main body including a hook provided to the base of the main body and adapted to be releasably engaged with the base side of the frame and allowing the clip to pivot relative to the base, the clip assembly further including a resilient detent having a distal end with a tab, a proximal end and a shoulder oriented to face generally towards the cushion and outward of the main body, the tab being configured to protrude through a slot located in the frame upon pivoting of the hook with respect to the frame so as to locate the shoulder against the frame.
