The silicone rubber is the reaction product of polyorganosiloxane bearing Si--H groups and polyorganosiloxane which bears Si--(CH.dbd.CH.sub.2) groups and which on average contains between 40 and 1000 monomeric units per polymer chain, bears 1.5-4 terminal vinyl groups, bears at most one non-terminal vinyl group per 80 monomeric units and contains at most 2% Si atoms in the form of SiO3/2 or SiO4/2 units. The thickness of the silicone rubber covering is preferably less than 500 micrometers.
