Fastening device and gas fuel storage assembly and vehicle and method

A fastening device for fastening a first and a second container to a structure of a vehicle, the fastening device comprising:

• an elongated member at least partly provided with external engagement members;
• a first abutment arranged concentrically with the elongated member;
• a displaceable member connectable to a first band member configured to extend at least partially around the first container and to a second band member configured to extend at least partially around the second container:
• a guide arrangement, comprising a second abutment;
• a holed member at least partly provided with internal engagement members;
• and
• a resilient compressible member positioned between the first abutment and the displaceable member or between the second abutment and the holed member,
• wherein the elongated member extends along an axis and the displaceable member, the guide arrangement, the resilient compressible member, and the holed member are aligned along the axis, and
• wherein the elongated member extends through the displaceable member and at least partially through the guide arrangement for engagement between the external engagement members of the elongated member and the internal engagement members of the holed member for compression of the resilient compressible member.
