Abstract
Abstract A connecting device for connecting together hollow members comprises a body having frusto-conically tapered bores and sleeves having bores of similar diameter to the outside diameter of members to be connected, said sleeves having complementarily tapered external surfaces for mating with the bores in said body so that a member carrying one of said sleeves can be passed through one of said tapered bores in said body and, by facing said sleeve into said tapered bore, positively connected to the body and to any other member or members similarly connected thereto.

Independent Claim
189 words
A connecting device for use in connecting together a continuous hollow bar and a hollow bar extending perpendicularly thereto comprising a body having a frusto-conically tapered continuous bore and a frusto-conically tapered blind bore arranged perpendicularly thereto, and a pair of wedge sleeves each having a bore whose diameter corresponds to the outer diameter of a hollow member that is to be connected, the outer surfaces of said wedge sleeves being frusto-conically tapered and complementary to said bores in said body, said wedge sleeve for said continuous bore being provided with a circular, radially projecting edge on its larger diameter, and said wedge sleeve for the blind bore having a hermetically sealing cover on its smaller diaemter end for sealing the end of a tube inserted therein, said bores of said body and of said sleeves being so designed that any one of said wedge sleeves surrounding a hollow member to be connected can be pressed in self-locking manner into a selected one of said bores in the body whereby the hollow member is clamped tightly to said body and to any other hollow member connected to said body.
