ABSTRACT:
A locking arrangement is for a receptacle and cover with overlapping parts and aligned holes through the overlapping part. A bolt extends into at least one of the holes with a handle at one end of the bolt for pulling the bolt out of the aligned holes in a withdrawing direction. An expansion mechanism at an opposite end of the bolt expands to prevent withdrawing the bolt. The mechanism has a contracted geometry for allowing withdrawing of the bolt. An actuator mounted for movement to the bolt is pushed to contract and unlock the mechanism. A spring biases the expansion mechanism toward the expanded geometry so that when the actuator is not being pushed, the expansion mechanism is in the expanded geometry to lock the cover to the receptacle.
