The first method is to use M1 detonating cord clips. The M1 detonating cord clip can be used to connect two
strands of detonating cord at right angles to each other, as shown in Figure 1-33. The angle formed by the branch
line and the ring main should not be less than 90 degrees in the direction from which the blast is coming.

In the second method, a detonating cord connector is used to join the branch line to the ring main, as shown in
Figure 1-34.
The third method is used in the absence of M1 detonating cord clips or detonating cord connectors. Branch lines
can be attached to the ring main using the girth hitch with one extra turn, as shown in Figure 1-35. Remember to
