Abstract:

A housing is provided including peripherally extending side walls and a fixed wall extending between one set of corresponding marginal portions of the side walls. The side of the housing opposite the fixed wall is open and a cover is provided for the open side of the housing. The cover and housing include structure operable to releasably lock the cover in a closed position. At least one of the side walls has a slot formed therein opening through the free edge thereof remote from the fixed wall and a link chain section composed of interconnected links includes at least one link intermediate the opposite ends of the link chain section which may be received through the slot. The chain section and the portions of the one side wall defining the slot include coacting structure preventing longitudinal displacement of the chain section through the slot. In this manner the end of the chain section disposed exteriorly of the housing may be anchored relative to a stationary object in order to prevent removal of the housing. Also, various structures are provided within the housing further locking additional links of the link chain section within the housing, whereby the slot in the side wall through which the one link extends does not comprise the sole structure for anchoring the end of the link chain section within the housing and to the latter.
