ABSTRACT:
A shipping container seal for joining two members having holes therein. The seal comprises a male member adapted to pass through the holes in one direction having an enlargement at one end to preclude the male member from slipping entirely through the hole. A female member cooperates with the male member to prevent retrograde motion. Once the male member and the female member are assembled, the female member has locking means cooperating with the male member to permit it to pass through the female member in one direction but precluding retrograde motion. The female member may comprise a plurality of inwardly extending projections or a plurality of half-barrel shaped inserts with spring means for retaining the half-barrel inserts in assembled relationship. A feature of the latter construction is the configuration of the spring means which includes a clip having first and second sections complementary to the half-barrel shaped inserts and a bridge including a roof portion which will expand and contract connecting the first and second sections. A further feature of the invention is the provision of a hood comprising a tubular housing for enclosing the male member and female member so as to prevent access thereto after the hood is assembled.
