An elbow connector (10,20) for use with a patient interface device (2) includes a coupling portion (11,21) structured to be inserted into an opening in the patient interface device to couple the elbow connector with the patient interface device. The coupling portion includes an upper coupling portion (11a) and a lower coupling portion (11b). The elbow connector also includes a rear surface (13). Applying pressure to the rear surface causes the upper coupling portion to move towards the lower coupling portion.
