Pull seal with bi-directional locking arrangement

A bidirectional lockable sealing device which comprises:

• a socket defining a first chamber therein,
• a shackle having an at least one locking element, the shackle being fixed at one end to the socket and having a free end opposite the one end;
• a locking insert secured to the socket in the first chamber, the locking insert including a body defining a second chamber therein having a longitudinal axis extending therethrough defining a longitudinal direction, the locking insert including opposing top and bottom ends where the top end defines a top opening communicating with the second chamber, and the bottom end defines a bottom opening communicating with the second chamber;
• and
• a plurality of resilient fingers positioned in the second chamber at least one first finger of the plurality extending from the top end and at least one second finger from the plurality extending from the bottom end toward the first finger, the fingers defining a passageway in the second chamber arranged to allow passage of the at least one locking element as the free end of the shackle is pulled through the passageway in an insertion direction via either the top or the bottom opening such that the fingers are in sliding resilient engagement with the at least one locking element, and wherein one of at least one first and second fingers is arranged to abut and lock to at least one of the locking elements of the shackle when the shackle movement is in an opposite direction to the insertion direction providing locking resistance to the shackle.
