Abstract: An assembly 10 includes a coupling member 12 having a first annular, radial connection flange 22 and a blanking cap 14 comprising a disc-like member 30 which defines a second, corresponding annular, radial connection flange 34. The connecting flanges are clamped together by a clamp (16) with a seal member 18 in-between. The blanking cap comprises a pair of safety lugs 62 attached to the disc-like member which each extend about an outer circumferential periphery of the first connection flange 22. Each safety lug has an abutment 68 for engagement with the first connection flange to limit axial movement of the disc-like member away from the coupling member. The lugs 62 prevent the blanking cap from flying off in the event the clamp is released whilst the interior of the coupling member is pressurised. The lugs 62 may each have a stop member 66 which defines the abutment and which may take the form of an elongate curved member extending circumferentially about an axis of the connection flanges. The clamp may be tri-clamp.
