Abstract: A clip element for removably attaching a protective cover to a linear bearing is disclosed. The clip element can be mounted on either the fixed support or the movable carriage of the linear bearing and comprises a resilient arm extending in spaced relationship to the component. The spacing is sized to receive an end of the cover inserted beneath the arm. The arm is resiliently attached to a mounting plate which facilitates mounting of the arm onto the bearing. The arm is resiliently biased toward the plate to removably retain the cover when it is inserted beneath the arm. Clip elements for use on the carriage are joined by elongated connecting members which extend between the mounting plates and position the clip elements at each end of the carriage. Clip elements are attached to the linear bearing by means of fasteners or double sided adhesive tape.
