A support assembly (2) comprising a mask frame (4) for a patient interface device； a headgear strap (6) structured to be connected to the mask frame； and an interconnect assembly (100, 300, 400). The interconnect assembly includes a number of female interconnect members (110, 210, 310, 410), a first body member (112, 212, 312) and a first magnet (116, 216, 316, 416) coupled to the first body member. The first body member is connected to the mask frame and has an aperture (114, 214, 314, 414). The interconnect assembly also includes a number of male interconnect members (150, 250, 350, 450), a second body member (152, 252, 352) and a second magnet (160, 260, 360, 460) coupled to the second body member. The second body member is connected to the strap member and includes a protrusion (154, 254, 354, 452, 454) structured to be located within the aperture. When the protrusion is located within the aperture, the first magnet is attracted to the second magnet, thereby removably connecting the first body member to the second body member.
