Abstract: The invention discloses several types of fastener, fastening systems, fastener assemblies and related areas. In particular, the invention discloses a releasable fastening system (150) which has a pin (152) with a locking cavity (163). The pin is intended for insertion in an aperture (154). A locking means (158, 160) engages the locking cavity (163) of the pin (152) when the pin (152) is received in the aperture (154). The system (150) also includes unlocking means (162) which includes material adapted to contract when activated. When a material contracts, engagement means (158) included in the locking means (158, 160), disengage the locking cavity (154).

Abstract: The invention relates to a releasable fastening system (10). The releasable fastening system (10) includes a fastening means having a pair of legs (12), at least part of the legs (12) being adapted for movement towards and away from a channel (16) between the legs (12). Each leg (12) has a foot (22) for engagement with external means (track) (26). The releasable fastening system (10) further includes means (wedge) (30) movable in the channel (16) between a locked position in which the feet (22) are in engagement with the external means (track) (26) and an unlocked position in which the feet (22) are disengaged from the external means (track) (26).
