ABSTRACT:
A locking device includes a shackle member and a key operable locking head that may be fastened onto a latch portion of the shackle member. The locking head has a housing and a rotatable retainer and a lock core in the interior of the housing. The lock core is mechanically coupled to the retainer, and both the retainer and the lock core are axially oriented with respect to an axial opening in the housing. The latch portion is axially insertable through the axial opening when the lock core is in an unlocked state and has a latch head which becomes fastened by the locking head when the retainer is rotated by the lock core into a locked state. A seal is supported by the housing proximately to the axial opening and acts to seal against a seal surface on the latch portion. The shackle member can be a linear portion with a stop portion, such as a knob, or alternatively, a cable member. The latch portion preferably has both a first profile that engages the axial opening to prevent relative rotation of the shackle member and the locking head and a second profile that extends through an aperture in the retainer. The first and second profiles are geometrically similar. A limit stop prevents rotation of the retainer through more than a selected arc.
