A system includes an upper connection having a ring shape with an external surface, where upper splines are formed on the external surface and the upper connection is fixed to the upper section. The system also includes a lower connection having a ring shape with an internal surface, where lower splines are formed on the internal surface and the lower splines are configured to mate with the upper splines of the upper connection. Further, the system includes a fishing sub having a first lateral end and a second lateral end, where the first lateral end is fixed to the lower connection by shear pins configured to shear when a pre-determined tension is applied to the system, and the second lateral end is fixed to the lower section. The upper connection is inserted into the lower connection to form an engagement between the upper section and the lower section.
