The line retension device includes a relatively thin plate having means defining an elongated passageway for receiving the line in a friction tight manner. The cross-sectional area of at least a portion of the passageway is complementary shaped and sized relative to the cross-sectional shape and size of the line. In one form of the invention, the passageway extends in a tortuous or non-linear configuration in the unstressed condition of the plate to grip the line frictionally. The plate is adapted to be flexed manually to deform it to a position where the configuration of the passageway is closer to that of a straight line, thereby permitting the line and the plate to be moved relative to one another in a much more facile manner.

A retension device for a line extending through a channel opening in a fabric material, comprising: a relatively thin, generally flat plate having a planar surface adapted to be sewn to the surface of the fabric material, and a cross-sectional area that is larger than the channel opening in the fabric material to inhibit passage of the plate into the channel opening; a raised cup-shaped portion defining an elongated passageway for receiving the line to be retained and for deforming readily responsive to pressure applied digitally; an upper ridge portion at least partially defining said passageway extending generally in a parallel spaced-apart manner relative to said plate for supporting frictionally said line over a substantial length thereof away from said plate to retain the line in an unstressed condition of the device; said passageway extending generally longitudinally throughout substantially the entire length of said raised portion, and having a tortuous configuration in the unstressed condition of said raised portion; said raised portion being integrally connected to said plate and composed of a single piece of plastic material; said raised portion being adapted to be flexed manually by a single digit of the hand of the user toward the plate, to deform into a position into closer proximity to said plate for decreasing the tension on the line and for straightening the configuration of said passageway, to a sufficient extent for permitting the line to be moved freely positionally relative to said plate; the cross-sectional area of said passageway being complementary shaped and sized relative to the cross-sectional shape and size of the line, to enable the raised portion to receive the line in a friction tight manner; said raised portion being of sufficient length to engage frictionally the line, and to inhibit relative movement of the line and said passageway; wherein said raised portion includes a pair of upstanding end walls and a pair of upstanding side walls; wherein said device is an integral one-piece construction; and said upstanding end walls and said upstanding side walls are interconnected by said ridge portion, said ridge portion being a longitudinally extending bight portion.
