Anti-extrusion elements to prevent extrusion of a sealing element during compression. The anti-extrusion element has a series of inner segments forming a loop bent to form a slot running along the circumference of the anti-extrusion element. The slot opens and faces radially outward away from the loop. Each inner segment has two ends on opposing sides aligned to form an opening between two inner segments. The anti-extrusion element additionally has a series of outer segments adjacent to one another to form a loop and slot. The series of inner segments is nested within the slot of the series of outer segments. Each outer segment comprises a peg within the slot and each peg aligns with a corresponding opening such that one peg protrudes through one opening. The anti-extrusion element additionally has a plurality of springs in the slot of inner segments and the springs are coupled to the pegs.
