Abstract
An earplug is described, which includes an elastic earplug body (12) and a metal part (14) mounted to the body to form an earplug that can be detected by a metal detector. The metal part (14) is in the form of a band that is clamped around the body. Where the body includes a narrow stem (24) and at least one flange (34) extending from a position (56) on the body and at a radially outward and rearward incline therefrom, the band can be attached to a location (62) lying a small distance rearward of the position where the flange emerges from the stem, so the band is hidden and is prevented from directly engaging a person's ear canal.
