A plug is adapted to be fixed by means of a hot melt adhesive into an opening in a plate. It comprises a molded plastics material body and a bead of hot melt adhesive deposited onto a peripheral surface of the body around a surface transverse to the peripheral surface. The body comprises at least one snap-fastener blade having an insertion ramp and a retaining lip such that the insertion ramp bears against the edge of the opening when the plug is placed on the latter, bends if pressure is then applied to the plug to press it into the opening, and expands thereafter with the lip facing a first side of the plate while the bead of adhesive faces a second side of the plate. The snap-fastener blade extends between an attachment end and a free end in a longitudinal direction parallel to the peripheral surface and to the transverse surface. The blade is therefore entirely on the second side of the plate when the plug is snap-fastened in place. The distance in the longitudinal direction between the attachment end and the free end is greater than the distance between the peripheral surface and the foot of the insertion ramp. |
