Device for securing a peripheral venous catheter

A device for securing a peripheral venous catheter, which includes an integral body (1) comprising a first fastening extremity (1.1), a second fastening extremity (1.2) and a connecting section (1.3) that interconnects the first fastening extremity (1.1) and the second fastening extremity (1.2), the first and second fastening extremities (1.1, 1.2) are tubular-shaped and comprise a first longitudinal groove (1.11) and a second longitudinal groove (1.21) respectively, such that through said first and second longitudinal grooves (1.11, 1.21) a portion of the catheter (2) may be inserted to be fastened in a folded manner as a safety loop (2.1) between the first and second fastening extremities (1.1, 1.2), wherein the connecting section (1.3) comprises a first portion (1.31) and a second portion (1.32) extending between the first and second longitudinal grooves (1.11, 1.21), in such a way that the first fastening extremity (1.1), the first portion (1.31) of the connecting section (1.3), the second fastening extremity (1.2) and the second portion (1.32) of the connecting section (1.3) form the body (1) with a contiguous closed perimeter outline that defines a contiguous hollow internal space (1.4) adapted to be set between a first open position and a second closed position, where, through the hollow internal space (1.4), in the first open position, the portion of the catheter (2) may be inserted for attachment thereof to the first and second fastening extremities (1.1, 1.2), and said portion of the catheter (2) being fastened at said first and second fastening extremities (1.1, 1.2) by arranging the hollow internal space (1.4) in the second closed position, wherein anchoring means from the first portion (1.31) to the second portion (1.32) of the connecting section (1.3), adapted to maintain the hollow internal space (1.4) of the body (1) in the second closed position, are a tongue-and-groove joint (1.5), wherein the tongue-and-groove joint (1.5) comprises a first recess-shaped part (1.51) arranged flush between sub-portions (1.311, 1.312) of the first portion (1.31) of the connecting section (1.3), and a second projection-shaped part (1.52) arranged raised from a centre of the second portion (1.32).
