ABSTRACT:
A downhole apparatus permitting separation of one part of downhole equipment from another part thereof includes a first part connected to a second part by a connecting member which limits axial and rotational movement of the first and second parts and has first and second ends connected respectively to the first and second parts. The connecting member includes a cross bar extending between the first and second ends having an aperture therein that results in a region of weakness, a portion of the cross bar spaced from the aperture minimizing stress at the region of weakness when torque is transmitted in use between the first and second parts via the connecting member.
