The holes made by striking out circular breaking indications (2) corresp. in size to that of the pipe connections to be connected. Also on the box wall are guide tracks (4) for connection of pipe connection fixture plates. The pipe connections each comprise two parts (5,6) which on delivery are held together by a thin material bridge (8). The two parts are telescopically displaceable, the outer (5) being firmly connected or assembled on the box wall with the aid of guide tracks (4) centrally for one of the circular break parts. The inner part (6) of the pipe connection is inserted into the outer part by a stroke to an extent that it breaks through the indicatory part in the box wall, and opens a connection. The inner part has lock components (7) which engage the outer part or possibly the box wall, so that the inner part is prevented from being drawn backwards. (Provisional basic advised week 87/07) |
