ABSTRACT:
A connecting member comprising an elastically deformable, tubular plug (1) slitted at the ends for interconnecting pairs of building components (9a,9b), which have coupling holes (8a,8b) to receive the ends of the connecting member, has apertures (3) in the plug wall between the slits (2), and the plug wall is formed with lengthwise extending clamping wedges (4) between the apertures (3), said clamping wedges having inclined faces which slope towards the ends of the connecting member and causing the connecting member to be compressed at the center and be expanded at the ends when it is pressed into a pair of co-axial holes in adjacent building components. The connecting member may in particular be formed with an annular flange (5) and end beads (6a,6b) which fit in corresponding annular grooves (7) in a pair of adjacent components (9a,9b).
