A clip assembly includes a support defining an opening and a clip attachable to the support. The clip includes a body configured to retain a conduit and a retention member extending from the body and having a first portion inserted through the opening to attach the clip to the support and a second portion engaging the support inside the opening to prevent rotation of the clip relative to the support. The retention member is movable between an initial position from which the first portion of the retention member elastically deforms as the first portion is inserted into the opening and a final position at which the first portion of the retention member has elastically deformed back toward an original configuration once the first portion has passed beyond the opening such that the second portion engages the support inside the opening to prevent rotation of the clip relative to the support.
