Brick fastening device

A device for fastening together bricks which have apertures to receive the device, the device comprising:

• elongated support means insertable into the apertures of two adjacent bricks;
• stop means extending outward from the support means, intermediate the extremities thereof, for engaging the adjacent bricks to limit penetration of each of the adjacent bricks by the device and to ensure penetration of both adjacent bricks by the device;
• and
• a plurality of resilient, longitudinally spaced transverse fins extending radially outward from and concentric with the support means so as to be in interference relationship with the adjacent bricks, the fins each being similarly configured and divided into a plurality of blades which extend radially out from the support means, the blades of adjacent fins being aligned to form longitudinal rows, and being resiliently deformable upon insertion of the support means into the apertures of the adjacent bricks such that the fins are biased outward into engagement with the adjacent bricks to restrain withdrawal of the device from each of the adjacent bricks;
• the support means comprising a shaft having a plurality of rounded lobes corresponding to the number of blades per fin, each lobe of the shaft being recessed from both sides laterally, and from the end radially, of the blades, and providing support for a row of fins at the central portion of the base of each blade.
