The lock is mounted for movement within the housing by mounting components connected to the lock by adhesive foam tape. One of the locking components includes a ramp making an angle generally about 30 degrees to the bottom of the housing for camming the shackle legs upwardly into operative association with the lock. At the top of the ramp upturned ears are formed which make an angle of about 30 degrees with respect to the direction of shackle movement to further cam the shackle legs into operative association with the lock.
