Abstract
Various implementations include a duct coupler including a body, a first and second arm, and a first and second tooth. The body has a first end that faces a first axial direction, a second end that faces a second axial direction, and a wall. The first and second arm each have a fixed end coupled to the second end and free end axially spaced apart from the fixed end. Each of the free ends are resiliently urgeable in a radial direction. The first tooth is coupled to the first arm, and the second tooth is coupled to the second arm. The teeth are shaped such that, when the teeth are engaged with a corrugation of a corrugated duct, the teeth allow the duct coupler to move in the first axial direction with less axial force than moving the duct coupler in the second axial direction.
