Fastening device for trapdoors and the like, characterized essentially by comprising on the sides of the frame the fixing of two pieces in "S" traversed longitudinally by two pins with head, disposing in one of the entrants of the pieces in "S" the respective spikes to be fastened and integral to the trap door, and the pin section passing through the other recess of the "S" part has a stop projection that makes the accidental exit of the pin impossible, however, allowing the partial sliding of the latter through of the corresponding holes in the "S" piece, when you want to release the fastener.
