In the title compound, C13H17N2O+.Cl-, homochiral cationic molecules are linked to form chains in the b-direction of the triclinic cell by N-HCl hydrogen bonds. The dihydro-2-furanyl groups are nearly parallel to the a axis [81.7 (1)° between the axis and the normal to least-squares plane] and the imidazoline rings are roughly perpendicular to it [25.5 (1)° between the axis and the normal to least-squares plane]. For details of polymorph I see Belin, Chauvet, Leloup, Ribet & Maurel [Acta Cryst. (1995), C51, 2439-2441].
