Abstract

A reusable device is presented for effecting a mechanical connection between two elements that are substantially coaxial, the elements subject to traction stresses with reference to each other, and the elements disconnectable beyond a specific traction threshold. The device includes a casing, with a first half and a second half, integrally connected to one of the elements, the casing having a cavity formed between said halves, and said casing comprising elastic material. The other element includes a bulge comprising, for example, a spherical swivel joint that is received in the cavity, the portion of said halves adjacent said cavity separable as the bulge passes into the cavity.

Claims

1. A device for providing mechanical connection between a first and a second substantially coaxial element that are mutually subject to traction, said device disconnectable beyond a specific traction threshold and reusable, comprising a male piece fixed to the end of the first element, so as to form a bulge at the end of the first element, and a casing integral with the end of the second element, said casing comprised of elastic material and including a cavity that substantially adapts to the form of said bulge removably received in said cavity, said casing includes a first half and a second half, said halves assembled along a joint plane parallel to an axis that is common to the elements, each of said halves have a central part and including means for securing the central part of said first half to the central part of said second half, and wherein said securing means includes at least one screw, and wherein said casing includes a metallic platelet in which the end of said screw is secured;

and wherein said cavity is located outside said central part, said cavity defined by adjacent ends of said halves, said ends separable from each other, and said central part being connected to the end of the second element.

2. A device in accordance with claim 1 wherein said bulge includes a portion of a spherical swivel joint.

3. A device in accordance with claim 1 wherein said second element includes an end having a collar that is encased in said casing, so that the second element is integral in translation with the casing, said second element swivelable in said casing.

4. A device in accordance with claim 1 wherein said casing includes an entrance orifice communicating with said cavity, and wherein said bulge includes a spherical swivel joint, said orifice having an internal diameter that is less than the maximum diameter of said bulge.
