Abstract

An apparatus may be used with an elongate member that includes an engagement member, a hollow shaft, a compression member, a compression element, and a resilient gripping member. The hollow shaft extends from the engagement member along a longitudinal axis. The compression member is slidably disposed over the hollow shaft. The hollow shaft is disposed over the resilient gripping member and supports the compression element. The compression member has a conical inner surface including a detent feature. The conical inner surface is configured to urge the compression element radially inwards as the collar advances from the unlocked position toward the locked position where the detent feature retains the compression element. The compression element deforms the resilient gripping member radially inwards to grip the elongate member and prevents translation of the elongate member. When unlocked, the resilient gripping member moves radially away from the elongate member allowing translation.
