The connection is made with ligaments and connective tissues. Below the lumbar spine is the sacrum. The sacrum is actually a group of specialized fused vertebrae that connects the spine to the pelvis.
The pelvis connects them.
Both males and females have a pelvis. It is the bony structure that connects the base of the spine to the legs, in humans. In other mammals it connects the base of the spine to the rear limbs.
The pelvis is made up of three bones; the ilium, the ischium, and the pubic bone. Attached to the back of the pelvis is the sacrum/coccyx which are two bones made of multiple vertebrae that are fused together. Also connected to the pelvic bone is the head of the femur (thigh bone) which sits in the acetabulum of the pelvis and creates the acetabulofemoral joint also known as the hip joint.

The sacral bone is a large, triangular bone at the base of the spine that forms the back of the pelvis. It is made up of five fused vertebrae and connects the spine to the hip bones. The sacrum plays an important role in providing structural support and stability to the spine and pelvis.
short answer - the sacrum and the base of the skull.
pelvis is a structure in the human skeleton system which contains a large compound bone structure at the base of the spine, this connects the legs or rear limbs.
The pelvis is located superiorly (above) to the patella. The patella, commonly known as the kneecap, is situated at the front of the knee joint, while the pelvis forms the lower part of the trunk and supports the spine and connects to the legs. Therefore, the pelvis is anatomically higher in the body than the patella.

The pelvis and spine are connected through the sacroiliac joint, which is located at the junction of the sacrum (part of the spine) and the ilium (part of the pelvis). This joint helps to transfer forces between the upper body and lower body, allowing for stability and movement.
The word relating to the hip is "pelvic." The pelvis is the bony structure located at the base of the spine, and it connects the spine to the femurs (thigh bones). Additionally, "coxal" refers specifically to the hip joint or hip bone.
The lumbar vertebrae in the lower back is typically five in number and unfused.
