A coupling device (1) including a first part (2) and a second part (3) is provided. The first and second parts are adapted to engage on another. The coupling device also includes an indicator seal (6) positioned on the first part. The indicator seal is visible when the coupling device is not fully engaged. Full engagement of the first and second part obscures the visibility of the indicator seal.
