摘要

An electric installation device has a support frame for a base (11) made of an electrically insulating material, and an expansion claw (15) which is laterally adjustable for fixing the installation device in a wall socket outlet. The tips (18) of the claw has a cover made of a material softer than that of the expansion claw so that during tensioning of the expansion claw the tips pierce the covering.
