Retainer (60) features a bridging portion (26) adapted to be disposed intermediate webs (34) and has resilient arms (28) at opposite ends that respectively extend towards and around trunnions (42) and thence towards and past portions (26) and thence outwardly to resiliently engage and releasably secure fastener (60) to webs (34) in which, in a preferred embodiment, the ends of the arms are shaped into helical coils (30) that are adapted to extend into openings (44) through each web (34). |
