Downhole coupling mechanism

A downhole coupling mechanism between a first end of a first tubular section being part of a downhole tool and a second end of a second tubular section;

• each end including one or more complimentary circumferential grooves machined in opposing surfaces to align when the first and second ends are arranged co-axially one inside the other;
• one or more wires, each wire being located within one of the circumferential grooves on the first end and a complimentary one of the circumferential grooves on the second end, so that each pair of complimentary grooves contains one wire extending around the circumference of the surface of each end, wherein the wires are continuous loops of square cross-section, and wherein each of the wires has a dimension in cross-section greater than a depth of the circumferential groove on the first end or the depth of the circumferential grooves on the second end where the wires locate;
• at least one lug and notch arranged on opposite of the first and second ends providing interlocking engagement when the first and second ends are arranged co-axially one inside the other;
• and
• one or more seals arranged between the opposing surfaces when the first and second ends are arranged co-axially one inside the other.
