Connecting sleeve for anchoring shafts of two oppositely arranged prostheses

A connecting sleeve for anchoring shafts of two oppositely arranged prostheses on an elongate bone, comprising a first receiving bush comprising a first fork, and a second receiving bush comprising a second fork, each of the first fork and the second fork extending from a side of the first receiving bush and the second receiving bush directed toward the coupling region, respectively, such that the first fork and the second fork together define a pair of forks that interact with each other, wherein each of the first fork and the second fork comprise fork tines and a fork base, wherein an inward surface of each fork tine is a fork flank,

• wherein the first receiving bush is configured to receive a shaft of a first prosthesis of the oppositely arranged prostheses, and wherein the second receiving bush is configured to receive a shaft of a second prosthesis of the oppositely arranged prostheses,
• wherein a separable coupling region is arranged between said first receiving bush and said second receiving bush and is connectable in such a way as to resist shear and rotation, wherein, the first receiving bush comprises:
• a first fitting block arranged at the fork base of the first fork,
• the second receiving bush comprises a second fitting block arranged at the fork base of the second fork, the first fitting block and the second fitting block arranged between the fork tines of each fork, lateral sides of the first fitting block are at a distance from each other corresponding to an inner width of the second fork, and wherein in a mounted state the flanks of either the first fork or the second fork are bearing in a planar manner on lateral sides of the other fork of the first fork and the second fork,
• wherein the first fork and the second fork are configured to be connected, and the lateral sides of the first fitting block and the second fitting block are inclined toward each other,
• wherein the first fitting block comprises a receiving bore configured to receive a fastener of the first fitting block,
• wherein the second fork comprises an opening configured to receive the fastener of the first fitting block,
• wherein the fastener is configured to extend through the receiving bore of the first fitting block and the opening of the second fork.
