A fastening element, comprising: a gripping portion having a gripping face and a back face opposite the gripping face, wherein the gripping face comprises at least one of a plurality of hooks and/or a plurality of loops; an anchoring portion comprising an anchor proximal end affixed to the gripping portion and an anchor distal end, the anchoring portion comprising at least one resilient clip configured to anchor the fastening element in a substrate with a retention force greater than an insertion force necessary for inserting the anchoring portion into a mounted position on a substrate, wherein the at least one resilient clip comprises: a clip proximal end located in proximity to the anchor distal end and a clip distal end located in proximity to the anchor proximal end; a compression portion extending from the clip proximal end and configured to cause a deflection of the at least one clip toward a longitudinal axis of the anchoring portion during insertion of the anchoring portion into a receiver of the substrate; a shoulder extending from a terminus of the compression portion toward the longitudinal axis of the anchoring portion; a retaining portion configured to exert a retaining force on the substrate based on the resilient action of the at least one clip, the retaining portion extending at a non-orthogonal angle from a position near the shoulder toward the clip distal end as measured relative to a radial axis of the anchoring portion wherein the fastening element further comprises rotational locking means configured such that upon turning of the fastening element within a through-hole of the substrate, the rotational locking means prevent the fastening element from turning further than a predetermined point, and further prevent turning the fastening element back to an insertion position wherein the rotational locking means comprises a ramp and abutment, wherein the ramp is configured to exert an increasing force on a portion of the substrate as the fastening element is rotated, and the abutment is configured to prevent further turning,. a gripping portion having a gripping face and a back face opposite the gripping face, wherein the gripping face comprises at least one of a plurality of hooks and/or a plurality of loops; an anchoring portion comprising an anchor proximal end affixed to the gripping portion and an anchor distal end, the anchoring portion comprising at least one resilient clip configured to anchor the fastening element in a substrate with a retention force greater than an insertion force necessary for inserting the anchoring portion into a mounted position on a substrate, wherein the at least one resilient clip comprises: a clip proximal end located in proximity to the anchor distal end and a clip distal end located in proximity to the anchor proximal end; a compression portion extending from the clip proximal end and configured to cause a deflection of the at least one clip toward a longitudinal axis of the anchoring portion during insertion of the anchoring portion into a receiver of the substrate; a shoulder extending from a terminus of the compression portion toward the longitudinal axis of the anchoring portion; a retaining portion configured to exert a retaining force on the substrate based on the resilient action of the at least one clip, the retaining portion extending at a non-orthogonal angle from a position near the shoulder toward the clip distal end as measured relative to a radial axis of the anchoring portion wherein the fastening element further comprises rotational locking means configured such that upon turning of the fastening element within a through-hole of the substrate, the rotational locking means prevent the fastening element from turning further than a predetermined point, and further prevent turning the fastening element back to an insertion position wherein the rotational locking means comprises a ramp and abutment, wherein the ramp is configured to exert an increasing force on a portion of the substrate as the fastening element is rotated, and the abutment is configured to prevent further turning,. a clip proximal end located in proximity to the anchor distal end and a clip distal end located in proximity to the anchor proximal end; a compression portion extending from the clip proximal end and configured to cause a deflection of the at least one clip toward a longitudinal axis of the anchoring portion during insertion of the anchoring portion into a receiver of the substrate; a shoulder extending from a terminus of the compression portion toward the longitudinal axis of the anchoring portion; a retaining portion configured to exert a retaining force on the substrate based on the resilient action of the at least one clip, the retaining portion extending at a non-orthogonal angle from a position near the shoulder toward the clip distal end as measured relative to a radial axis of the anchoring portion wherein the fastening element further comprises rotational locking means configured such that upon turning of the fastening element within a through-hole of the substrate, the rotational locking means prevent the fastening element from turning further than a predetermined point, and further prevent turning the fastening element back to an insertion position wherein the rotational locking means comprises a ramp and abutment, wherein the ramp is configured to exert an increasing force on a portion of the substrate as the fastening element is rotated, and the abutment is configured to prevent further turning,.
