Abstract

A multiple access locking device is provided which is capable of being opened by any different number of users. The device includes first and second receptacle members and an elongate locking bar which, when removed from the receptacle members, allows the receptacle members to be moved relative to each other. The first receptacle member includes a tab with an opening therein and the elongate locking bar includes a similar tab with an opening. A plurality of coupling segments are placed on the locking bar between the tabs of the first receptacle member and locking bar. The coupling segments are identically configured and define a pair of radially extending tabs each having an opening for receiving a lock. Accordingly, a plurality of locks is placed through the respective openings and any one lock can unlock the multiple access device.
