A film wind-up spool for receiving developed x-ray and other photographic film comprising a cylindrical body and a removable flanged head associated at the one end of the body. The flanged head connects to a resilient insert which fits within the interior of the body at the end thereof to removably secure the head to the body. The insert flexes from an initial, unstressed position wherein it may be readily inserted into and removed from the end of the body to a second, binding position wherein it locks within the body to secure the flanged head to the end of the body.
