摘要

The device has a holder (2), which is designed as a ring-shaped body at whose inner wall an inset (3) is provided. The holder has an insertion region for insertion of a flat object of utility. A disc (1) e.g. chip, is inserted into the inset such that the disc is clamped in the body. A clamping beaded rim (4) is provided at a distance from the inset for holding the disc, where the distance corresponds to the disc thickness.
