Downhole tool assembly

An assembly for connecting a production tubing to a packer, the assembly comprising:

• a first body having a blocking member disposed in a slot;
• and
• a second body having a lug configured to engage the blocking member in the slot,
• wherein the first body is configured to be coupled to one of a packer and a production tubing, and wherein the second body is configured to be coupled to the other one of the packer and the production tubing, such that the first body and the second body are together configured to provide a connection between the production tubing and the packer, and wherein the blocking member is configured to block the lug from moving in the slot until the lug applies a predetermined force onto the blocking member.

A connection for connecting together a packer and a production tubing, the connection comprising:

• a first body having a helical slot and a blocking member that obstructs an entrance to the slot;
• and
• a second body sized to be received into the first body and comprising a lug configured to be received into the slot,
• wherein the blocking member is configured to prevent the lug from entering the slot,
• wherein the blocking member is configured to be removed by a predetermined force applied by the lug onto the blocking member, and
• wherein the first body is configured to receive the lug into the slot by rotating the first body relative to the second body once the blocking member is removed.
