Abstract
In an engine housing and transmission housing adapted to be moved axially together, an easily actuatable and releasable attachment means for joining the housings coaxially together so as to prevent relative rotation and axial separation. Retention grooves cut through interfitting non-rotation splines on the housings provide oppositely facing limit surfaces, with one retention groove also providing a pocket for an expandable and contractable retention ring. In a stored position, the ring is located outside of the root of the splines, so that the housings may be pushed together without resistance, which also serves to align the retention grooves. The ring is then contracted by a single turnable fastener, moving it out of the pocket and between the oppositely facing limit surfaces to prevent axial separation of the housings.
