Abstract
The present technology relates to a headgear for a patient interface, comprising one or more straps each having a first end for connecting to a mask. The first end of each strap comprises a connection portion which is grippable by a user to pull the strap to increase a tension in the strap, a first rigid member and a second rigid member that extends from a resilient carrier that is connected to the connection portion. The second rigid member is movable relative to the first rigid member when the connection portion is pulled. At least part of the second rigid member is arranged to strike the first rigid member to cause at least an audible alert when the second rigid member travels further than a threshold distance. The resilient carrier is constructed and arranged such that the threshold distance corresponds to a desired tension limit for the strap.
