At least one end of a rucksack frame member (22 or 23) may be secured to a fabric sack (21) by being accommodated in a passageway defined by a raised portion (12) of a fastening device (10), a further portion (11) of which is fixed to the sack (21). Movement of the frame member end through the passageway is limited by abutment against a stop member in the form of a resilient flange (13) projecting into the passageway. However, during assembly of the rucksack in the case where the frame member is a bar (22 or 23), it can be inserted right through the passageway, past the stop member (13), the latter springing back to block the passageway once the trailing end of the bar has passed thereby.
