A hair clipper includes a handle portion having a drive end with a first coupler
formation, and a blade assembly. The blade assembly includes a housing at least
partially enclosing a reciprocating blade and a fixed blade, and having a top,
bottom, and at least two sides joining the top and bottom. Integrally joined to
and extending away from the bottom of the housing is a second coupler formation
for engaging the first coupler formation. The first and second coupler formations
form a releasable connection which inhibits movement of the blade assembly with
respect to the handle portion when the two coupler formations are engaged.
