<p>The disclosure relates to a lock suitable for a refuse bin for securing a cover of the bin to a base of the bin. The lock comprises a body to be mounted on the cover and having a spring loaded projecting plunger to engage the base. The plunger has an inclined cam surface disposed within the body and a key is insertable in the body to engage the cam surface. The key has two spaced longitudinally extending abutments to engage the cam surface in succession to provide an initial and then a final retraction of the plunger. A projection is provided on the lock body adjacent the plunger to engage between the abutments on the key and thereby prevent a simple blade from being used to retract fully the plunger.</p> |
