The friction of the rope against the screw on the carabiner can cause the screw to undo and the carabiner to open, potentially weakening the strength of the carabiner, or allowing the rope to escape the carabiner completely. Therefore the hitch has to be tied correctly with the braking end on the opposite side of the carabiner than the gate is.

A carabiner or karabiner (/ ˌ k ær ə ˈ b iː n ər /), [1] often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate [2] used to quickly and reversibly connect components, most notably in safety-critical systems.
A particular variation is whether the gate is locking, which gives extra security when belaying but makes the carabiner heavier and slightly tricker to clip into, or non-locking, which is the easiest to clip into and out of for example when leading a bolted sport climbing route but with the risk that the gate may unintentionally open.

Gimbal lock is the loss of one degree of freedom in a multi-dimensional mechanism at certain alignments of the axes. In a three-dimensional three- gimbal mechanism, gimbal lock occurs when the axes of two of the gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space.
A breech-lock is a system for mounting camera lenses to camera bodies. The lens is attached to the camera by means of a rotating ring which is used to tighten the lens to the camera by friction. [1] Other methods for mounting a lens to a camera include bayonet mount or thread mounts. With breech-lock, the body of the lens does not rotate ...
