Abstract: A fastening member for fastening a net to a tubular post has, on the one hand, a holder portion (2) for fixedly retaining the net and, on the other hand, an anchorage portion (1) for fixedly retaining the fastening member in the post. The anchorage portion (1) extends in through a hole in the wall of the post and is provided with barbs (7,9) which snap in place in the fastening member. The anchorage portion (1) has a longitudinal passage (4) in communication with an accommodation space (3) in the holder portion (2). The passage (4) has a funnel-shaped flared mouth portion (5) to facilitate insertion of a wire included in the net in the accommodation space (3). On insertion of the wire, the passage (4) is flared in that the wall (12,13) of the holder portion (2) facing away from the passage (4) is resiliently bendable.
