The downhole device having a first component, the surface of the first component having a first protrusion. Each of the locking arms being deformable away from the longitudinal axis, one or more gripping protrusions extend out from an outer surface of the locking arms, and at least one second protrusion extends from an inner surface of the locking arms. The inner surface is engageable with the surface of the first component to deform the locking arms away from the longitudinal axis. Upon engagement, the at least one first protrusion engages the at least one second protrusion to secure the collar to the downhole device.
