Abstract: A fastener assembly for securing first and second members (12, 14) to one another includes a cylindrical body (16) to be received and secured within a sheath (40). The cylindrical body includes a pair of longitudinal recesses (30, 32) extending in its external surface, and a spherical member (24) extending from the end thereof. The sheath includes a cylindrical bore (42) for receiving the body with a pair of ribs (44, 46) extending into the bore for alignment with the recesses. The spherical member extends from the sheath and is slotted (26) for retention against an outer surface (14a) of the second member. The ribs taper from an enlarged end (58) to be frictionally secured within the recesses for axial retention and anti-rotation.

Abstract: A fastening device is disclosed comprising a first fastener member adapted to be fixed to a sheath and a second fastener member adapted to be fixed to a support. One of the fastener members has a semi-cylindrical socket and the other fastener member has a cylindrical body adapted to engage the socket and be supported thereby for rotary movement. Axial retention means on the cylindrical body and socket prevent their relative axial movement while detent means also thereon engage with each other upon relative rotary movement therebetween and thereafter yieldingly prevent such relative rotary movement therebetween while holding the cylindrical body in the socket.
