A hand-held implement selectively usuable as a blower or a vacuum. A power-driven impeller moves an airstream through an impeller chamber from an intake port to an outlet port. A pair of coaxial rims surrounds the intake port to form a peripheral groove that can receive the end of a pipe and restrain it from lateral movement. An axial pull device can draw the pipe to hold it in the groove.

In a hand-held implement selectively provided for a blowing or a vacuuming operation, having a body housing, an impeller chamber having an intake port and an outlet port, a power driven impeller in said chamber for moving an airstream into said intake port, through said chamber and out through said outlet port, and a vacuum pipe to be removably connected to said body to conduct air from a free end of said vacuum pipe to an end thereof which surrounds said intake port, the improvement comprising: a pair of coaxial rims on said body surrounding said intake port, having different diameters so as to form a peripheral groove between them so proportioned and arranged as to receive said free end of said pipe and restrain it from lateral movement; axial-pull connector means comprising a first part connected to said body and a second part connected to said vacuum pipe, whereby drawing said parts together with said means draws said pipe axially toward and holds it against said body in said groove.
