Abstract: A lock for securing a trailer hitch includes a latching member, a position-limiting assembly, and a housing. The position-limiting assembly includes first and second position-limiting members, a magnetic member, and a securing pin. The first position-limiting member is configured for detachable engagement with the latching member. The second position-limiting member is mounted in the housing, receives the magnetic member, and is slidably connected to the first position-limiting member via the securing pin in order to be moved to an engaged position and a disengaged position. When at the engaged position, the second position-limiting member is mounted to the latching member due to the magnetic member and thereby fixes the first position-limiting member in position. When at the disengaged position, the second position-limiting member is separate from an end portion of the latching member to allow detachment of the first position-limiting member from the latching member.
