A fastener for fastening a first element to a second element comprising: a first part; a second part fastenable to the first part via a first fastening mechanism; and a third part fastenable to the second part via a second fastening mechanism. The third part comprises at least one protruding member for inserting thereof to the second element for fastening the second element between the second and third parts. The first fastening mechanism is configured such that to open the fastening of the first part to the second part an external tool such as a key or a magnet should be applied.

Apparatus and method of locking two devices to each other through a receiver base, a pair of pivoting locking tabs, each having first and second arms extending out from a pivot point, and an insert that is partially engaged within a cavity formed by the receiver base and locking tabs. The receiver base is configured to be engageable with a first device. The insert is configured to be engageable with a second device. An optional push button assembly that has a retractable lip is engageable with the receiver base to block rotational movement of the locking tabs unless the lip of the push button is retracted. The apparatus may also include magnetic actuators and corresponding electronic switches that provide two stage locking and, optionally, provide contact state signaling to an external controller and computer to verify locked/unlocked status of the insert relative to the receiver base cavity and locking tabs.

A connector for connecting inner and outer layers of an apparatus. The connector includes an anchor point connectable to the inner or outer layers. A resilient portion surrounds the anchor point about a first axis and connected to the anchor point. A peripheral portion surrounds the resilient portion about a second axis and connected to the resilient portion and connected to the other of the inner and outer layers. An attachment means on a surface of the connector opposite to the anchor point attaches the connector to the inner or outer layer not connected to the anchor point. The resilient portion protrudes from the peripheral portion deforms to allow the anchor point to move relative to the peripheral portion in a direction perpendicular to the first direction.

A snap thru grid fastener system for mesh fabrics wherein a snap thru grid component goes through the openings of the mesh fabric and is affixed to the indentations of the receiving component. The snap thru grid fastener system allows for the user to accessorize mesh fabrics without sewing the patch directly to the fabric or relying on single pin systems.
