A cable element attachment system (300) attaches cable elements (80) to an entrance/exit location (140) of an enclosure (100). The system includes a base (600) and a clamp (700). The base attaches to the entrance/exit location and includes at least one slot (630), first gripping features (672), and a first attachment feature (664). The slot extends to an open end (632). The clamp includes second gripping features (772) positioned opposite of the first gripping features. Each of the gripping features grips the cable elements. The clamp further includes a second attachment feature (764) that attaches the clamp to the first attachment feature. The entrance/exit location may include a seal arrangement (500) that seals the cable elements to the entrance/exit location. The gripping features may deform the cable element both around its circumference and along its path and thereby retain the cable element.
