Abstract
A downhole tool for sealing a well includes a push ring, a first slip ring located adjacent to the push ring, a first wedge located adjacent to the first slip ring and configured to radially push the first slip ring and separate the first slip ring into individual parts, and a sealing element located adjacent to the first wedge and configured to seal the well. An upstream end of the first slip ring and a downstream end of the push ring form a wavy interface when in contact. The wavy interface locks the first slip ring relative to the push ring to prevent a rotation of the first slip ring relative to the push ring.
