Abstract: A security seal includes a locking element and a locking body configured to receive an end of the locking element therein to secure the security seal at an object. The locking body may include a deformable wall that deforms responsive to a sufficient pressure applied to the wall of the locking body. A disk element may be disposed in the locking body and movable along a tapered channel to clamp against the locking element to limit retraction of the locking element. The tapered channel may have an arcuate surface along which the disk element moves to provide a progressively increasing bite angle and clamping force at the locking element. The disk element may have a knurled surface with a circumferential groove established circumferentially around the disk element, with the circumferential groove offset from a center line of the disk element and toward a respective end of the disk element.

Abstract: A security device includes a securement washer having a securement washer hole, and a circumferential groove within the hole. An end cap includes a well that contains the securement washer, and an end cap circumferential wall that extends around the securement washer. A portion of the end cap circumferential wall extends over a circumferential portion of the securement washer located around the securement washer hole. The portion of the end cap circumferential wall comprises tamper-evident indicia on a surface thereof. The tamper-evident indicia is formed so as to remain unchanged until and unless the security device is tampered with. The security device may be manufactured by forming tamper-evident indicia such as a disturbance on a surface of an end cap such that the indicia remains unchanged until or unless the security device is tampered with. The tamper-evident indicia may be formed by an orbital forming process.
