## Abstract

A cable splice, tube joint, or the like, is covered by a fitting constructed as a split hose provided along one edge with a rail made of metal or a strong synthetic; a similar rail element or an integral fastening element is provided on the other edge and secured to the first rail by welding, adhesive bonding, or soldering in order to obtain a joint which resists tension and compression. The hose has been laterally slipped onto and over the cable splice or tube joint and, after the split joint has been sealed (or concurrently therewith), the hose is heat-shrunk. Various rail configurations are shown; a method of making the hose is explained.

## Claims

### Claim 1

A hose-like fitting for covering cable or tube joints, connection zones, splices, or the like, comprising:
a split hose element made of a heat-shrinking synthetic material and having edges defining a split joint;
first and second rail means positively connected respectively to the edges and extending radially outwardly from the hose element, each of the rail means being made of metal to be mechanically a stronger material than the hose; and
the first and second rail means being metallically bonded to each other directly to effect a connection therebetween which is resistant to compression and tension.

### Claim 2 (depends on 1)

A fitting as in claim 1, the rail means being anchored and embedded in the hose material.

### Claim 3 (depends on 2)

A fitting as in claim 2, the rail means being of an L-shaped configuration.

### Claim 4 (depends on 1)

A fitting as in claim 1, including a flap which extends peripherally from one of the edges, under the other one.

### Claim 5 (depends on 1)

A fitting as in claim 1, at least the rail means having a plurality of slots for improving flexibility of the rail means.

### Claim 6 (depends on 1)

A fitting as in claim 1, both rail means being made of metal being soldered together.

### Claim 7 (depends on 6)

A fitting as in claim 6, at least one of the rail means being provided with means for retaining solder, prior to soldering.

### Claim 8 (depends on 7)

A fitting as in claim 7, the rail means being integrally embedded in the edge material.

### Claim 9 (depends on 2)

A fitting as in claim 2, wherein the rail has spread legs for being anchored in the hose material.

### Claim 10 (depends on 2, 3)

A fitting as in claim 2 or 3, wherein the rail has a dovetail-like portion for being embedded in the hose material.
