ABSTRACT:
A thermoplastic housing has a chamber open at one end and a thermoplastic rotor inserted in the chamber. The housing wall contains bores aligned across the chamber and two annular grooves in the chamber adjacent the chamber entrance. Tabs are formed adjacent the chamber entrance. The rotor has a bore and two annular ridges near its top. The ridges are relieved complementarily to the tabs. The rotor is inserted and locked axially in the housing by snapping the ridges into the grooves. The tabs are located in the relieved areas to align all of the bores so that a seal wire may thereafter be inserted through the bores. The rotor includes flexible spiral-like co-planar pawl teeth which engage ratchet teeth formed on the housing in the chamber. The ratchet and pawl teeth rotationally lock the rotor relative to the housing while permitting the rotor to bend a seal wire inserted in the bores during rotation which rotation in one direction locks the rotor. The ratchet and pawl teeth may also be used align the bores for insertion. The rotor is rotated manually by a hand-operated tool such as a screwdriver. With a seal wire inserted, the rotor and housing are relatively rotated to wrap the wire about the rotor. Each ridge snaps into one groove when the rotor is inserted into a corresponding housing.
