Headgear connectors and headgear for use with or comprising part of a user interface assembly

A headgear configured to be secured to a patient interface of a respiratory therapy system, to mount the patient interface on a user's head, the headgear comprising:

• at least one strap having a first end and a second end opposed along a longitudinal axis of the at least one strap;
• wherein:
• the first end of the at least one strap being configured such that the first end of the at least one strap can be looped back to form an overlapped strap portion;
• the second end of the at least one strap, opposed to the first end, extending from a strap connecting region of the headgear;
• the at least one strap having an effective strap length being the distance extending between an apex of the overlapped strap portion and the strap connecting region of the headgear;
• the at least one strap comprising a strap length adjustment mechanism comprising a hook and loop fastener arrangement configured to releasably engage a portion of the at least one strap to form the overlapped strap portion, wherein a size of the overlapped strap portion can be adjusted to adjust the effective strap length by engaging the hook and loop fastener arrangement with a different portion of the headgear;
• the hook and loop fastener arrangement comprising a plurality of discrete hook and loop fastener regions, each of which has an engaging surface and is secured along its entire length to a strap surface of the at least one strap, wherein the plurality of hook and loop fastener regions are spaced apart along the longitudinal axis of the at least one strap such that there is an exposed strap surface in a gap between each pair of the hook and loop fastener regions, wherein the engaging surface and the exposed strap surface face in a same direction, wherein the engaging surface of each of the plurality of hook and loop fastener regions comprises a first portion of the hook and loop fastener arrangement and the exposed strap surface between each pair of the hook and loop fastener regions comprises a second portion of the hook and loop fastener arrangement, the first portion configured to be releasably connectable with the second portion.
