A variation of coax cable (RG6) clip often used outdoors or wherever extra hold strength is required. The cable is slid between the two flat plates until it 'snaps' into the rounded channel. The clip is then screwed or otherwise anchored to a structure, which also tightens it's grip around the cable sheath.

I tested one with PLA, low infill (20%ish) and inserted cable more than 30 times with little to no structural degradation. Anchored cable to a beam and the clip takes enough force to damage cable
