Abstract

Ear plug of the type comprising a capsule of compressible and reexpandable foam or expanded material 1 coated with a flexible bag-like sheath 2, characterised in that the bag-like coating sheath is open on the outside opposite the side in which the plug 21 is inserted in such a way that it can be seized between the fingers D and tightened after compressing the capsule to reduce it to a minimum diameter prior to insertion, in such a way that when insertion is complete access of air to the interior is prevented in order to permit subsequent reexpansion only on release. <IMAGE>
