ABSTRACT:
In builders scaffolding of the kind wherein cross-members are detachably connected to upright members by connecting means comprising a plurality of open-ended vertically disposed sockets on the upright member and connector means on the cross-members each comprising a pair of vertically spaced limbs adapted to embrace a selected socket member, with a wedge clamping member driven through aligned openings in the limbs of the connector member and through the socket to press the end faces of the limbs into engagement with the upright member, an improved connector member in which the two limbs are spaced apart by a distance sufficient to receive a socket therebetween with only a small clearance, at least the upper limb affording a cavity at its underside to accommodate a retaining formation which is provided on the lowermost end of the wedge clamping member so that the latter may be raised to a releasing position in which its lowermost end is clear of the space between the two limbs.
