The ATLAS detector requires upgrades to exploit the physics potential of new HL-LHC, where the large increase of pile-up interactions is a main challenge. The High-Granularity Timing Detector (HGTD) will be built in order to mitigate the effects of pile-up in the ATLAS forward region, providing a time resolution of about 30 ps per track. A 2x4 cm2 Low Gain Avalanche Detector (LGAD sensor) bump-bonded to two ASICs and glued to a flexible PCB, make up the so-called module, the HGTD basic unit. The active area consists of 2-doubled-sided disks per end-cap and is surrounded by the Peripheral Electronics Boards (PEB). A Flexible Printed Circuit (Flex tail) serves as connection between a module and the PEB: power, communication signals and HV bias. A demonstrator is proposed to test the functionality and assembly of a subset of components of the full detector such as electronics, sensors and the cooling system as part of the R&D phase. A Flex tail prototype is planned to be tested during the demonstrator activities. An overall description of the demonstrator activities with emphasis on the Flex tail is presented.
