Retaining device
Abstract:
A retaining device includes a fireproof core enclosed by a non-fireproof case, wherein a pre-tensioned fireproof device is integrated in the case and attached to the core. The fireproof device relaxes in such a way, when the case melts, that a construction element is reliably held between the carrier and the device.
