Abstract: An assembly, including a cable and a bracket, is configured to secure a firearm having a shell ejection slot. The bracket, including a front plate and a tail, is configured for partial insertion into the shell ejection slot. The tail is disposed at an acute angle relative to the front plate and comprises a first aperture configured for insertion of the cable. A method of securing a firearm includes inserting a tail of a bracket into the shell ejection slot so that a front plate of the bracket remains outside the shell ejection slot, inserting a first end of a cable through a first aperture of the tail, and retaining the first end of the cable in a notch of a firearm holder.

Abstract: A double wall pipe assembly includes an inner primary pipe (4) and an outer secondary pipe (5), as well as a novel fitting assembly (3) for terminating the double wall pipe assembly. The primary pipe is a flexible annularly corrugated pipe made from stainless steel which is flexible and nearly impermeable to fuels. The fitting assembly provides an integrated seal of the secondary pipe to a fastener (8) used to seal the primary pipe to fitting body. The fitting assembly may also maintain communication between an interstitial space between the primary and secondary pipes and an access port (182) in the fastener. The access port can be used for monitoring of the interstitial space between the primary and secondary pipe.
