A snap-on door sweep is attached to a door in an operative position with a gripping engagement within opposed door grooves to provide a seal between th e bottom door surface and a door opening threshold when the door is disposed i n a closed position within the door opening. The sweep includes a relatively rig id attaching structure to be attached to the door in cooperating relation to th e horizontal grooves and the bottom surface thereof when the snap-on door swee p is in the operative position with respect thereto. The sweep also includes a relatively flexible threshold engaging seal assembly carried by the attaching structure in a position to extend downwardly therefrom when the snap-on door sweep is in th e operative position thereof. The attaching structure includes a bottom wall portion operatively disposed below the bottom surface of the door when the snap-on door sweep is in the operative position and a pair of groove engaging portions fixed to opposite sides of the bottom wall portion and extending inwardly in spaced relation thereto. One of the pair of groove engaging portions constitutes a snap-on portion having a cam portion fixed thereto. The pair of engaging portions ar e operatively engaged in the horizontal grooves when the sweep is in the operative position thereof to grippingly retain the same therein. The sweep is manuall y moved into the initial position thereof wherein the cam portion is engaged with the door adjacent the bottom door surface and one side thereof in generally coextensive relation therewith. The cam portion includes a cam surface such that when the sweep is moved from the initial position thereof into the operative position thereof the cam surface engages the door and moves the snap-on portion outwardly and allows it to move with a snap action into the operative positi on thereof as the sweep reaches the operative position thereof.
