Thank you for contacting Biobidet Support.
The BB-600 "slides" onto the mounting plate/catch plate. You will not hear per sae a click but more "feel" a click when sliding onto the plate. Best to use forwards and backwards on each side movements while pushing the bidet onto the plate. There is not a release button like the premire models such as a BB-2000.
If you should need further support, please contact us at firstname.lastname@example.org
