The handle housing is provided with a longitudinal support having, relative to a conventional operating position of the implement, a front end face that is disposed transverse to a longitudinal axis of the longitudinal support. A securement end of a front tubular handle rests against and is secured to the front end face of the longitudinal support. ## Claims ### Claim 1 A manually guided implement, comprising: an engine housing; a handle housing, wherein said engine housing and said handle housing are interconnected by means of anti-vibration means, wherein said handle housing is provided with a longitudinal support having, relative to a conventional operating position of said implement, a front end face that is disposed transverse to a longitudinal axis of said longitudinal support, and wherein said front end face is disposed at an angle of from 0 to 20° relative to a line perpendicular to said longitudinal axis; a front tubular handle having a securement end that rests against and is secured to said front end face of said longitudinal support; and a clamping element, wherein said securement end of said tubular handle is positively held between said front end face of said longitudinal support and said clamping element, wherein said clamping element is in the form of a clamping shell that surrounds said securement end of said tubular handle, wherein at least one securement screw is provided for effecting a screw connection of said securement end of said tubular handle to said front end face of said longitudinal support, wherein said at least one securement screw is disposed perpendicular to a plane of said front end face and hence is disposed at least approximately in the direction of said longitudinal axis of said longitudinal support, and wherein said clamping element is provided with a point of attachment for said anti-vibration means. ### Claim 2 (depends on 1) An implement according to claim 1, wherein said longitudinal support has a cross-sectional height (H) that corresponds at least approximately to a cross-sectional height (h) of said securement end of said tubular handle. ### Claim 3 (depends on 1) An implement according to claim 1, wherein at least a grip region of said tubular handle has a circular cross-section having a grip diameter (D), and wherein a cross-sectional height (h) of said securement end (8) of said tubular handle corresponds to said grip diameter (D) thereof. ### Claim 4 (depends on 1) An implement according to claim 1, wherein said clamping shell at least nearly entirely surrounds said securement end of said tubular handle. ### Claim 5 (depends on 1) An implement according to claim 1, wherein a securement sleeve is provided for receiving a securement screw, and wherein said securement end of said tubular handle has a receiving bore that surrounds said securement sleeve in a manner that is at least approximately free of play. ### Claim 6 (depends on 5) An implement according to claim 5, wherein said securement sleeve is disposed on a clamping element. ### Claim 7 (depends on 6) An implement according to claim 6, wherein said securement sleeve is monolithically formed with said clamping element. ### Claim 8 A manually guided implement comprising: an engine housing; a handle housing, wherein said engine housing and said handle housing are interconnected by means of anti-vibration means, wherein said handle housing is provided with a longitudinal support having, relative to a conventional operating position of said implement, a front end face that is disposed transverse to a longitudinal axis of said longitudinal support, and wherein said front end face is disposed at an angle of from 0 to 20° relative to a line perpendicular to said longitudinal axis; a front tubular handle having a securement end that rests against and is secured to said front end face of said longitudinal support; and at least one securement screw for effecting a screw connection of said securement end of said tubular handle to said front end face of said longitudinal support, wherein said at least one securement screw is disposed at least approximately perpendicular to a plane of said front end face and also in the direction of said longitudinal axis of said longitudinal support, wherein said securement end of said tubular handle is formed of polymeric material, wherein a screw-receiving means is formed in said securement end for said securement screw; and wherein a point of connection for said anti-vibration means is monolithically formed on said securement end of said tubular handle. ### Claim 9 (depends on 8) An implement according to claim 8, wherein the entire tubular handle is made of polymeric material. ### Claim 10 (depends on 8) An implement according to claim 8, wherein a molded part for positively securing a position of said securement end of said tubular handle relative to said front end face of said longitudinal support is monolithically formed on said securement end.
