A lockable security cover 1 is provided to prevent or hinder access to a telephone distribution frame 7. As shown in Figure 1 the substantially rectangular cover 1 is shaped to fit over the frame 7 which has tabs 8 on which connector blocks for telephone wiring are mounted; the side portions 5 of the cover may allow access for the wires. Securement means 9, 12 has rods 12 firmly secured to frame base by screws through apertures 18 in a member 75 at the base of the frame. The lower end of the rods 12 prevents access to the screws holding these bars. One or more key-operated locking bars 2 having a terminal stepped tongue 70 can slide beneath transverse bar 9 and into a recess 69 formed in an abutment member 20 inside the cover; the bar is then lockable against sliding movement by (a) locks 3 in the top 4 of the cover so as to prevent access to the frame. Different arrangements (Fig. 4 to 9) are shown for securing the rods 12 to the frame. A single locking bar can rotate to fit under hoops fitted over the frame (Figs. 10-11). <IMAGE> |
