ABSTRACT:
A building entrance protector unit (20) includes plurality of electrical connectors (86) providing electrical connections between wire pairs (104, 105) leading from telephone stations of subscribers in the building and wire pairs (57,58) from the local telephone networks serving the unit, these connections being interruptible by the subscribers for the purpose of plugging in their telephone sets to the network to test these sets. The connections are tamperproofed by a hasp mechanism (87) providing hasp leaves (130) respective to these connectors and each lockable in a first position impeding access to the corresponding connection by attachment of a padlock (170) to a hasp staple (150) projecting through that leaf. That locking may be overridden by a telephone network technician by a releasing from a held position of a common mounting (111) for all the hasp staples. The staples are hook shaped so that, upon such releasing, a closed padlock can be removed from any staple by closing relative movement between the mounting for the staple and the leaf through which such staple projects. The hasp leaves are plastic and at their held ends (131) have partly open resiliently expandable sockets (146) adapted to fit over and be removed from a hinge pin (110) by snap fitting action. To override the lock means, a crank arm (167) is moved out of engagement with a loop (160) that extends below the common mounting.
