PCT No. PCT/AU87/00358 Sec. 371 Date Apr. 25, 1989 Sec. 102(e) Date Apr. 25, 1989 PCT Filed Oct. 23, 1987 PCT Pub. No. WO88/03231 PCT Pub. Date May 5, 1988.A fastener for sheet material includes a fork member mounted on a fixture and having a pair of outwardly diverging arms, and a keeper member which is placeable in a locking position between the arms. A portion of sheet material disposed between the fork member and the keeper member is held therebetween even when a tensioning force is applied to the portion, since the portion thereby applies a torsional force to the keeper member to bias the keeper member into a locking position within the fork member. |
