A connector for a shoring system comprises a housing adapted to be mounted on a frame which is to be connected to legs which define the plurality of axially extending channels (15). The housing slidably receives a bolt (30). The bolt (30) has a head shaped and dimensioned so that in one orientation axial movement of the bolt may introduce the head through the slot (6) into the channel, and in an alternate orientation the bolt may not be withdrawn from the channel (15) by axial movement. The bolt is associated with means adapted to rotate the bolt and to move the bolt axially relative to the housing. <IMAGE> |
