Hotpoint WD440 - how to remove the Jubilee Clip?

My washer dryer has begun to leak water from the drawer during the rinse and spin stage. I understand I should check the black rubber unit attached to the outlet pipe but it is fixed to the machine by a solid white jubile clip at either end. How do I remove this to clean the rubber unit? The clip is white plastic with crocodile teeth grips. Also can I assume it is reusable to that when I remove it I can rattach it....if so....how?
