PCT No. PCT/SE80/00311 Sec. 371 Date Jul. 20, 1981 Sec. 102(e) Date Jul. 20, 1981 PCT Filed Dec. 3, 1980 PCT Pub. No. WO81/01773 PCT Pub. Date Jun. 25, 1981.An arrangement in a telecommunications system for fitting a connection block in a cover so that a complete connecting unit is obtained, which can be connected to the front edge of a circuit board or in the back plane of a rack containing circuit boards. The arrangement is characterized by a cover formed so that a standardized connection block can be inserted into the cover guidance via guiding pins in the cover through the screw holes in the block normally used for screwing the block to the cover. The cover is provided with resilient end walls from which bosses project towards the interior of the cover. When the block is inserted into the cover, the end walls (3) deflect outwardly but reassume their original position when the block is engaged against stops in the cover, the projecting bosses engaging over the edges of the short ends of the connection block to lock the block to the cover.
