A substrate 16 can be sealed by a recoverable sleeve 18 or other means which is supported by a support 1 which surrounds the substrate 16. The support 1 has a projection 2 which extends through a hole in the sleeve 18 to provide communication from the support 1 to the outside of the assembly. The projection may serve to locate the sleeve, to provide a pressure access point or to provide for electrical connection. |
