Abstract:
Clip of thermoweldable material (11) for a conduit also comprised of weldable material, comprised of at least two shells (10) surrounding the conduit in the position of use, and wherein the shells (10) have longitudinal flanges (17, 19) facing one another in pairs in the position of use, which can be connected to one another under pressure, wherein the shells (10) have at least one electrically heatable conductor (21) arranged in continuous windings (25) at inner surfaces (15) of the shells (10), and wherein the windings (25) of the conductor (20) extend, on the one hand, only in a semi-circular zone (12, 121) at the inner surfaces (15) in two end areas (31, 31') of the shell (10), respectively, and, on the other hand, extend also between these two semi-circular zones (12, 12') in a planar strip (13),whereinthe shells (10) with respect to their shape and the arrangement of the conductor (21) are the same or identical, and for a paired use of the shells (10) in the clip are positioned so as to face one another and rotated relative to one another, wherein the strip (13) is arranged only at the inner surface (32) of one of the longitudinal flanges (17), and electrical terminals (18, 28) are provided which are formed integrally on the outer side (14) of each shell (10), wherein the conductor (21) projects with a part of its cross-section (22) from the contact surface (15, 32) of the semi-circular zones (12, 12') on the shell or the strip (13) on the longitudinal flange, and a positive locking connection is provided between the conductor (21) and the material of the shell (10).
