Abstract

The device for closely securing two insulator segments around a support member includes a resilient brace secured to and connecting the spaced apart insulator segments, a pair of converging upper locking surfaces and contiguous diverging lower surfaces on the insulator segments. A locking bar having a top and a pair of converging sides is conformingly inserted within the brace and upper locking surfaces in order to mechanically secure the insulator segments around the support member. A refractory mortar is applied to the interior of the locking plug and the diverging lower surfaces in order to protect the locking plug from the furnace heat. The arrangement permits the insulator segments to be locked at a single point around the support member.
