ABSTRACT:
A block connecting link for round steel chains includes two identical stirrup-like link halves each having an essentially rectangular cross-section and a rear surface without projections, planar side surfaces, convexly curved end surfaces and receiving means for round chain links located adjacent the transverse middle plane and facing the middle plane of division between the link halves. At one end of each link half is provided a projection which protrudes beyond the middle plane of division, wherein the projection includes a convex bracket protruding at a distance toward the adjacent end surface, and at the other end of the link half a projection which also protrudes beyond the middle plane of division and has a concave recess adapted to the bracket and arranged at a distance from the adjacent end surface. Protruding from the projection with the recess in the area between the recess and the adjacent end surface is a pin with a transverse bore for a locking pin, wherein a pocket adjacent the projection with the bracket is adapted to the locking pin, wherein the pocket is located in the area between the bracket and the end surface adjacent the bracket. The principal axes of the brackets, the recesses, the pins and the pockets extend in the same direction and are inclined at the same angle relative to the transverse middle plane.
