Unitized security seal

A unitized security seal comprising:

• a shackle;
• an engagement housing with a passage for receiving the shackle;
• at least distal, intermediate and proximal members spaced along the shackle,
• each of the members having at least one undercut opening to the member outer surface;
• at least one pin located within the engagement housing passage oriented to be received and guided through the undercut of the distal member, pass through the undercut of the intermediate member and rest adjacent the undercut of the proximal member, the proximal member preventing further insertion of the shackle and the intermediate member engaging the pin to prevent disengagement of the shackle from the housing;
• and
• the undercuts of the members being offset from each other, including an entry opening and an exit opening, the entry opening being larger than the exit opening, with the undercuts including an angled ramp wall intersecting the entry and exit openings, the ramp wall being positioned to engage the pin as the shackle is advanced through the engagement housing, whereby the engagement of the ramp wall with the pin causes the shackle to rotate as it is advanced.

A unitized security seal comprising:

• a shackle;
• an engagement housing with a passage for receiving the shackle;
• at least distal, intermediate and proximal members spaced along the shackle,
• each of the members having at least a pair of diametrically opposed undercuts opening to the member outer surface,
• the undercuts of the members being offset from each other;
• and
• a pair of opposed pins located within the passage to be received and guided through the undercut of the distal member, pass through the undercut of the intermediate member and rest adjacent the undercut of the proximal member, the proximal member preventing further insertion of the shackle and the intermediate member engaging the pins to prevent disengagement of the shackle from the housing.

A unitized security seal comprising:

• a shackle;
• an engagement housing with a passage for receiving the shackle;
• at least distal, intermediate and proximal members spaced along the shackle,
• each of the members having at least a pair of diametrically opposed undercuts opening to the member outer surface including generally parallel entry and exit openings at opposite ends of the undercuts, the entry openings being larger than the exit openings, and an angled ramp wall intersecting the entry openings and exit openings,
• the undercuts of adjacent members being offset from each other;
• and
• a pair of opposed pins located within the passage oriented to be received and guided through the opposed undercuts of the distal member, pass through the undercuts of the immediate member and rest adjacent the undercut of the proximal member, the proximal member preventing further insertion of the shackle and the intermediate member engaging the pins to prevent disengagement of the shackle from the housing.

A unitized security seal comprising:

• a shackle;
• an engagement housing with a passage for receiving the shackle;
• a strap positioned between the shackle and the engagement housing;
• at least distal, intermediate and proximal members spaced along the shackle,
• each of the members having a pair of diametrically opposed undercuts opening to the outer surface of the members;
• the undercuts of adjacent members being offset from each other;
• and
• a pair of opposed pins located within the passage to be received and guided through the undercuts of the distal member, pass through the undercuts of the intermediate member and rest adjacent the undercuts of the proximal member, the proximal member preventing further insertion of the shackle and the intermediate member engaging the pins to prevent disengagement of the shackle from the housing.

• a pin located within the passage be received and guided through the undercut of the distal member, pass through the undercut of the intermediate member and rest adjacent the undercut of the proximal member, the proximal member preventing further insertion of the shackle and the intermediate member engaging the pin to prevent disengagement of the shackle from the housing,
• the pin including a base and a first spur extending distally from the base and at least the intermediate member including a second spur, the first and second spurs being positioned to interlock to resist rotation of the shackle.
