摘要

The device has a spring (30) and a groove (32) arranged at side walls (28) of the device, where the device is made of hard foam. Plug-in elements (22, 24) are provided at upper and lower sides of the device. An upper side of one plug-in element corresponds to a lower side of the other plug-in element such that the device is fitted to the other device. The spring has extensions corresponding to its protruding ends. The plug-in elements are arranged in corner regions. The groove is formed with undercuts corresponding to the extensions.
