A seal is provided for a connector which must be reliably sealed in applications where the connection is made and undone as part of the normal use of the connector. The seal is particularly well suited to on-off tools used in downhole applications. The seal comprises of a nonmetallic insert holding bonded seals, preferably made of rubber. The nonmetallic insert provides support against seal extrusion. It also does not damage the sealing surface if movement or flexing result in contact between the insert and the opposed sealing surface.
