Claims
- 1. A locking device comprising:
- an elongate member having on one end a neck portion of a first diameter supporting a head of a second diameter greater than said first diameter to define a shoulder therebetween; and
- a lock body securable to said elongate member, said lock body including
- a body member having an annular recess therein,
- a retainer fixed to said body member to overlie said recess and having a hole therethrough at least as large as said second diameter,
- first and second locking jaws within said recess and movable between a first position providing an opening of said first diameter and a second position providing an opening of said second diameter,
- said locking jaws defining bottom surfaces substantially perpendicular to said elongate member when secured to said lock body,
- means for supporting said locking jaws above the bottom of said recess, and
- means for biasing said locking jaws toward said first position, whereby said locking jaws bottom surfaces abut against the elongate member shoulder when the elongate member and lock body are secured together.
- 2. The locking device of claim 1, wherein said elongate member comprises a rigid member having an enlarged section on its other end and a bend intermediate its ends.
- 3. The locking device of claim 2, wherein said bend is 180.degree. and the end opposite said one end is slidably received within a hole in said lock body.
- 4. The locking device of claim 1, wherein said elongate member includes a flexible portion.
- 5. The locking device of claim 4, further comprising a flag member fixed to the other end of said elongate member.
- 6. The locking device of claim 4, wherein the other end of said elongate member is fixed to said lock body.
- 7. The locking device of claim 1, wherein said locking jaws form a collar around said neck portion when the device is locked.
- 8. The locking device of claim 1, wherein said supporting means and said biasing means comprise a U-spring with two legs interconnected by a cross member and supporting said locking jaws on respective legs of said spring.
- 9. The locking device of claim 8, further comprising a recess shoulder defined by a reduced diameter portion at the bottom of said recess, said cross member being supported by said recess shoulder.
- 10. The locking device of claim 9, wherein said leg members are shorter than the elongate member head so that said head bends said cross member between said recess shoulder to hold the leg members and supported locking jaws in said first position when the device is locked.
- 11. The locking device of claim 1, wherein said neck portion is supported on a first elongate member portion substantially as long as said retainer is thick and further comprising a second elongate member portion larger than the first member portion to define an end facing shoulder, said shoulder abutting said retainer when said device is locked.
