ABSTRACT:
A fastener for joining together two components includes a closure pin permanently securable to a first component and a receptacle disposed on the far side of a second component. The closure pin has a head section adapted for support in an outer side of the first component and a shank section extending through a hole in the first component and a hole in the second component aligned with the hole in the first component and having a thread mating with an internal thread in a fastening section of the receptacle. The peripheral surface of the closure pin has a radial taper zone with a stop face radially extended on the opposite side from the head section and formed by a rim stop. The stop face engages with a safety element to prevent complete extraction of the closure pin from the hole in the first component. The safety element is disposed in a groove open to the hole in the first component. Removal of the pin is made possible by making the outer diameter of the rim stop sufficiently smaller than the outer diameter of the rim stop sufficiently smaller than the outer diameter of the shank section outside the taper zone to allow insertion therebetween of a hollow cylindrical section of a releasing tool that fits around and over the rim stop and the taper zone until the latter is covered. The outer diameter of the releasing tool is equal to or smaller than the outer diameter of the shank section outside the taper zone.
