Generally opposite the hinge the lid includes a retention member (35), the retention member includes or defines a window (39) and includes a retention portion for engagement with a cooperating portion on the closure and/or on a container neck for holding the lid in a closed position. The closure includes a tamper-evident member (40) at least part of which moves into or out of view with respect to the window to indicate opening of the closure.
