FIELD: medicine.

SUBSTANCE: invention relates to medicine, mainly to physiotherapy, namely to massagers, and is used to enhance blood circulation in the treatment of arthrosis of the joints of parts of the arms and legs, is used to connect spring non-circular spirals to each other or the two ends of one spiral in a closed loop or to attach the spiral to any other product. A clip for a non-circular spring spiral to enhance blood circulation in the treatment of arthrosis of the joints of parts of the arms and legs is a part with radial annular grooves for installing the extreme turns of a non-circular spiral in them, chamfers at the edges of the part, collars that do not allow the spiral turns to jump between the grooves. The radius of the ducts R1 = 7 (1.05 ÷ 2.0)*R4 mm, where the radius of the wire R4 = 0.15 ÷ 0.4 mm, from which the spiral is made, and the collars have a radius R3 = R2 + (0.1 ÷ 0.9)*R4, where R2 is the installation radius of the clip.

EFFECT: use of the invention makes it possible to increase the reliability of the connection of the ends of a spring non-circular spiral, accelerating the connection of its ends and maintaining the flexibility of the connection.
