摘要： A lock has a keeper plate for attachment to a first relatively moveable part of the trunk, which keeper plate has a peripheral rim bounding a circular keeper opening and having a slot formed therein. An attachment plate is affixed to a second relatively moveable part of the trunk, while a hasp member is hingedly connected at one to the attachment plate and adapted at the other end to overlie the peripheral rim and the keeper opening when in a mated position. A hollow cylindrical bolt housing of cup-shaped configuration is fixed to and projects rearwardly of the hasp member. The bolt housing includes a cylindrical wall having a bolt opening therein positioned to align with the slot when the hasp member and the latching plate assume the mated position. A latching bolt is supported in the bolt housing for movement along an axis paralleling a diameter of the bolt housing, and has a free end portion aligned with the bolt opening. A spring continuously biases the free end portion to project through the bolt opening for automatically interlocking with the slot. A semi-annular lever is mounted behind the keeper plate substantially concentric with the keeper opening, and is pivotable about one end to move the bolt radially inwardly against the spring to free the bolt from the slot in the rim around the keeper opening.
