Locks for use with pest-control devices such as bait stations or other loadable devices, kits that include a lock and key, and pest control devices that include a lock.

The invention relates to a lock device, having a first connecting module and a second connecting module. The first connecting module can here be arranged in a closing direction on the second connecting module and is mechanically catch-lockingly engaged in a closing position with the second connecting module, and the first connecting module can be detached from the second connecting module by a movement of the first connecting module or of a part of the first connecting module in an opening direction, which differs from the closing direction. Here, a locking device (7; 9, 9a-f) is provided to prevent a movement of the first connecting module (1) or of the part (1a) of the first connecting module (1) in the opening direction (Y), when the first connecting module (1) and the second connecting module (2) are positioned in the closing position, wherein the locking device (7, 9, 9a-f; 100, 101, 102; 206, 207) can be unlocked to move the first connecting module (1) or the part (1a) of the first connecting module (1) in the opening direction (Y).

A locking system comprising a handle mounted such that it can rotate about an operating spindle, wherein the handle can move between a locked position and an unlocked position, a hook mounted on the handle and secured in rotation therewith, wherein the hook has a throat in which a latching point of a structure is designed to engage when the handle is in the locked position. The locking system comprises a key associated with the hook and by means of which it is possible to pass from the locked position to the unlocked position of the handle, wherein the key can be removed when the handle is in the locked position and cannot be removed when the handle is in the unlocked position.

A retention mechanism for retaining a lock cylinder in a lock housing. The retention mechanism includes a control lug, a control pin, and a finger pin. A portion of the control lug is configured to be positioned in a retention recess of the lock housing when the control lug is in an engagement position to prevent the removal of the lock cylinder from the lock housing. With the control lug in the engaged position, at least a portion of the control pin may be biased into a chamber of the control lug to retain the control lug at the engaged position. When the control lug is to be displaced from the engaged position, the finger pin may be lifted to an activation position, such as by a sidebit of a key, wherein the finger pin may removably displace the control pin from at least a portion of the chamber.

A latch has a displaceable latching element in a housing for engagement with a separate striker arm to be latched behind an engagement shoulder of the latching element. The housing mounts a cylinder lock to receive a key from the front. A rotor is mounted on the rear of cylinder lock and rotation of the key rotation the rotor to drive a locking element to engage and lock the latching element. The rotor may also be axial displaceable against spring biasing responsive to a rear unit pushing element whereby unlocking from a rear cylinder lock may rotate the rotor to unlock and pushing causes the latching element to be displaced against its biasing to release the striker arm. Embodiments include a gravity biased and manually opened latch and a spring biased self-locking embodiment.
