A gripping device for retaining a cable, the gripping device comprising: - a base, - two opposed gripping arms (10, 20) projecting from the base towards respective end portions (11, 21) along an insertion direction (Z-Z) and mutually spaced apart along a transversal direction (Y-Y) perpendicular to the insertion direction (Z-Z), the end portions (11, 21) defining an insertion opening through which the cable firstly passes upon insertion of the cable along the insertion direction (Z-Z) between the gripping arms (10, 20), the gripping arms (10, 20) having retaining portions (12, 22) configured to receive a cable therebetween and insertion portions (13, 23) configured to allow insertion of a cable towards the retaining portions (12, 22), the gripping arms (10, 20) extending between a first portion (14, 24) and an opposed second portion (15, 25) along a longitudinal direction (X-X) perpendicular to the insertion direction (Z-Z) and the transversal direction (Y-Y) to receive therebetween the cable extending along the longitudinal direction (X-X), - first protrusions projecting from the retaining portions (12, 22), extending along a first direction (A-A) angled with respect to the insertion direction (Z-Z) and configured to act on a cable to retain a cable between the retaining portions (12, 22), - second protrusions projecting from the insertion portions (13, 23) and extending along a second direction (B-B) angled with respect the insertion direction (Z-Z), each second protrusion being tapered along the insertion portion (13, 23) towards the respective end portion (11, 21) and - the first protrusions and the second protrusions are joined at a connection portion (16, 26); wherein - each gripping arm (10, 20) comprises an elastic portion (17, 27) connected to the base and configured to elastically deform the insertion portions (13, 23) and the retaining portions (12, 22) along the transversal direction (Y-Y) upon insertion of a cable; - the gripping device is realized in one piece in plastic or in metal material. - a base, - two opposed gripping arms (10, 20) projecting from the base towards respective end portions (11, 21) along an insertion direction (Z-Z) and mutually spaced apart along a transversal direction (Y-Y) perpendicular to the insertion direction (Z-Z), the end portions (11, 21) defining an insertion opening through which the cable firstly passes upon insertion of the cable along the insertion direction (Z-Z) between the gripping arms (10, 20), the gripping arms (10, 20) having retaining portions (12, 22) configured to receive a cable therebetween and insertion portions (13, 23) configured to allow insertion of a cable towards the retaining portions (12, 22), the gripping arms (10, 20) extending between a first portion (14, 24) and an opposed second portion (15, 25) along a longitudinal direction (X-X) perpendicular to the insertion direction (Z-Z) and the transversal direction (Y-Y) to receive therebetween the cable extending along the longitudinal direction (X-X), - first protrusions projecting from the retaining portions (12, 22), extending along a first direction (A-A) angled with respect to the insertion direction (Z-Z) and configured to act on a cable to retain a cable between the retaining portions (12, 22), - second protrusions projecting from the insertion portions (13, 23) and extending along a second direction (B-B) angled with respect the insertion direction (Z-Z), each second protrusion being tapered along the insertion portion (13, 23) towards the respective end portion (11, 21) and - the first protrusions and the second protrusions are joined at a connection portion (16, 26); wherein - each gripping arm (10, 20) comprises an elastic portion (17, 27) connected to the base and configured to elastically deform the insertion portions (13, 23) and the retaining portions (12, 22) along the transversal direction (Y-Y) upon insertion of a cable; - the gripping device is realized in one piece in plastic or in metal material.
