Abstract
Abstract A plastic corrugated sheathing hose adapted for electric cable installation and producible in one continuous operation, includes a longitudinal slit along its side. Each edge of the hose adjacent the slit is complementarily configured to form a detent or snap-locking closure releasably engageable in overlapping relationship. After insertion of a cable through the sheathing hose slit, closure of the hose is accomplished by pressing overlapped complementarily configured together. Closure of the hose in this manner results in a substantially gas-tight and waterproof cable enclosure accomplished in one operation with the inlaying of the cable.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
A corrugated sheathing hose of plastic, intended for electric installation, having a longitudinal slit along its side, comprising: means, disposed along the longitudinal slit, for releasably connecting the two edges of the hose adjacent the slit, said connecting means defining a snap-locking closure including a detent recess which is continuous in the longitudinal direction and a corresponding detent protrusion, said detent protrusion having a detent nose disposed thereon and said detent recess including a corresponding undercut, said connecting means including opposing side walls, said side walls defining a longitudinal recess therebetween having an asymmetrical V-shape, said slit being located near, but offset from, the lowermost portion of said recess thereby forming said detent nose.
Claim 2
Dependent Claim
114 words
A corrugated sheathing hose of plastic, intended for electric installation, having a longitudinal slit along its side, comprising: means, disposed along the longitudinal slit, for releasably connecting the two edges of the hose adjacent the slit, said connecting means defining a snap-locking closure including a detent recess which is continuous in the longitudinal direction and a corresponding detent protrusion, said detent protrusion having a detent nose disposed thereon and said detent recess including a corresponding undercut, said connecting means including opposing side walls, said side walls defining a longitudinal recess therebetween having an asymmetrical V-shape, said slit being located near, but offset from, the lowermost portion of said recess thereby forming said detent nose.
Claim 3
Dependent Claim
53 words
A corrugated sheathing hose as defined in claim 1, wherein the inclination of one of said side walls of said recess relative to said lowermost portion is greater than the inclination of the other side wall, and said slit is offset from said lowermost portion in the direction of said other side wall.
Claim 4
Dependent Claim
53 words
A corrugated sheathing hose as defined by claim 1, wherein said longitudinal slit is disposed in said hose in a direction inclined relative to a radial direction of said hose such that the face of said detent nose at said slit forms an acute angle with the outer surface of the longitudinal recess.
Claim 5
Dependent Claim
31 words
A corrugated sheathing hose as defined by claim 2, wherein an adjoining longitudinal bulge of approximately U-shaped cross section is disposed between said one side wall and said hose outer surface.
Claim 6
Dependent Claim
31 words
A corrugated sheathing hose as defined by claim 3, wherein an adjoining longitudinal bulge of approximately U-shaped cross section is disposed between said one side wall and said hose outer surface.
Claim 7
Dependent Claim
35 words
A corrugated sheathing hose as defined by claim 1, characterized in that one of the side walls defining said detent recess is thicker in cross section than the other of said detent recess side walls.
Claim 8
Dependent Claim
35 words
A corrugated sheathing hose as defined by claim 2, characterized in that one of the side walls defining said detent recess is thicker in cross section than the other of said detent recess side walls.
Claim 9
Dependent Claim
35 words
A corrugated sheathing hose as defined by claim 3, characterized in that one of the side walls defining said detent recess is thicker in cross section than the other of said detent recess side walls.
