connector

This EN 362: 2004

connector, a component

of the harness, is a

connecting element for

linking the chest harness

to the seat harness. Do not

use it to attach a lanyard

the connector must always

be used with the gate

closed and locked. The

strength of the connector

is greatly reduced if the

gate is open.

Systematically verify the

gate is closed by pressing

it with your hand.
