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.

[ I claim:] [17.] A locking device, comprising:(a) a key operable locking head movable between a locked state and an unlocked state and including a housing having an opening and an interior, a retainer and a lock core disposed in said housing, said lock core mechanically coupled to said retainer and having a keyway adapted to receive a key whereby rotation of the key acts to rotate said lock core thereby moving said retainer to define the locked state and the unlocked state, said locking head including a seal disposed proximately to the opening in surrounding relation thereto; and(b) a shackle member including a latch portion configured for insertion into the locking head through the opening to define a mated state and configured to engage said locking head, said latch portion including a latch head operative to mate with said retainer when said locking head is in the unlocked state yet configured to prevent withdrawal from said locking head when said locking head is moved to the locked state whereby said latch portion is captured by said locking head to define a fastened state, said latch portion including a seal surface, said seal engaging said seal surface when said locking head is in the fastened state thereby to prevent ingress of unwanted substances through the opening and into the interior of said housing.
